Abstract

An image forming apparatus includes a photoreceptor (1), a charging device (2) that charges a surface of the photoreceptor, an electrostatic charge image forming device (3) that forms an electrostatic charge image on a charged surface of the photoreceptor, a developing device (4) that develops the electrostatic charge image formed on the surface of the photoreceptor with a developer containing a toner to form a toner image, an intermediate transfer member (20, 50) to which the toner image formed on the surface of the photoreceptor is transferred, a primary transfer device (5) that transfers the toner image formed on the surface of the photoreceptor to a surface of the intermediate transfer member, a secondary transfer device (26) that transfers the toner image transferred to the surface of the intermediate transfer member to a surface of a recording medium (P), and an intermediate transfer member cleaning device (30) that has a cleaning blade (60) coming into contact with the surface of the intermediate transfer member and cleans the surface of the intermediate transfer member, in which the intermediate transfer member has a surface layer (52) containing a resin, a conductive agent, and a silicone oil, a silicon element concentration on a surface of the surface layer is 0.5 atm% or more and 10.0 atm% or less, a tip angle of the cleaning blade is 95 degrees or more and 110 degrees or less, and a tip hardness of the cleaning blade is 86 degrees or more and 96 degrees or less.
