The inkjet recording apparatus (100) includes a recording head (1), a cleaning member (2), a container member (3) which, by being pressed from above to below, is displaced from a first position to a second position and which, while in the second position, accepts supply of detergent, and a supply member (5) which is placed above the container member (3) to supply the container member (3) with the detergent. The container member (3) includes a containing part (31) for accepting supply of the detergent, and a base part (32) which adjoins the containing part (31) in a first direction (D1) perpendicular to an up/down direction. The supply member (5) presses the base part (32) from above to below without making contact with the containing part (31) so that the container member (3) is displaced from the first position to the second position.

The inkjet recording apparatus (100) includes a recording head (1), a cleaning member (2), and a container member (3). The container member (3) includes a containing part (31) which has an upwardly opening recessed area (310) and in which detergent supplied from above is contained in the recessed area (310), and a base part (32) which adjoins the containing part (31) in a first direction (D1) perpendicular to an up/down direction. The containing part (31) has a discharge hole (311) extending through the recessed area (310) in the up/down direction, and supplies the cleaning member (2) with the detergent flowing out downward from the discharge hole (311). An upper surface (32S) of the base part (32) is higher in liquid repellency to the detergent than an upper surface (31S) of the containing part (31).

A fixing device (8) includes a fixing belt (81), a sliding member (85), a nip forming member (84), and a pressing member (82). The sliding member (85) is sheet-form and is disposed radially inward of the fixing belt (81) to be adjacent to it such that the inner circumferential surface of the rotating fixing belt (81) makes contact with, while sliding across, the sliding member (85). The nip forming member (84) is disposed radially inward of the fixing belt (81), across the sliding member (85) from the inner circumferential surface of the fixing belt (81). The nip forming member (84) has a surface-roughened portion (842) formed on the surface of contact with the sliding member (85). Reduced Peak Height (Rpk) in the surface-roughened portion (842) is 2.5 [µm] or more but less than 500 [µm].

A fixing device (8) includes a fixing belt (81), a sliding member (85), a nip forming member (84), and a pressing member (82). The sliding member (85) is sheet-form and is disposed radially inward of the fixing belt (81) to be adjacent to it such that the inner circumferential surface of the rotating fixing belt (81) makes contact with, while sliding across, the sliding member (85). The nip forming member (84) is disposed radially inward of the fixing belt (81), across the sliding member (85) from the inner circumferential surface of the fixing belt (81). The coefficient of static friction between the sliding member (85) and the nip forming member (84) is 0.3 or more.

An intermediate transfer belt is a hard resin belt, and a developer carrying member includes a rotatable development sleeve and a magnet. The development sleeve carries a developer, and a magnetic brush is formed on its surface. In the magnet, a plurality of magnetic poles that are fixed in the development sleeve so as not to rotate and include a main pole disposed in a development region opposite an image carrying member relative to the direction of rotation of the development sleeve are spaced at predetermined intervals in a circumferential direction. A horizontal magnetic force gradient in a position where the horizontal magnetic force of the main pole is 0 [mT] is A, |A| ≥ 3.74 is satisfied.

One of a holding portion (221) and a grip portion (222) includes an inner tube portion (2221) that is tubular and extends from an end part thereof in an axial direction toward the other of the holding portion (221) and the grip portion (222) to be located within the outer tube portion (2211). The holding portion (221) is connected to the grip portion (222), via an elastic member (223) disposed within the inner tube portion (2221), so as to be vibratable in the axial direction. The outer tube portion (2211) includes an opening (2211a) that penetrates the outer tube portion (2211) in a radial direction thereof. The inner tube portion (2221) includes a protrusion (2221a) that protrudes from an outer surface of the inner tube portion (2221) so as to be located within the opening (2211a). When the holding portion (221) vibrates, the protrusion (2221a) moves in the axial direction within the opening (2211a).

A sheet drying apparatus (10) includes a conveyance portion (20), a drying portion (40), and a control portion (90). The conveyance portion (20) conveys a sheet (P) on which an image has been formed with ink containing moisture. The drying portion (40) has a heater (43) that heats the sheet (P), and includes a heating unit (41) that can be raised and lowered between a heating position for heating the sheet (P) with a heater (43) and a retracted position away from the conveyance portion (20), and a unit ascent-descent mechanism (87) that raises and lowers the heating unit (41). When a jam of the sheet (P) is detected between the conveyance portion (20) and the heating unit (41), the control portion (90) turns off the supply of power to the heater (43), stops the conveyance portion (20), arranges the heating unit (41) at the heating position until the temperature in the heating unit (41) falls below a first temperature, and, after the temperature in the heating unit (41) falls below the first temperature, raises the heating unit (41) from the heating position to the retraction position.
