Abstract

An image forming apparatus (1) includes a photoconductor drum (4), an intermediate transfer belt (5) that moves in contact with the photoconductor drum (4), and a primary transfer roller (31) that transfers a toner image on the photoconductor drum (4), therefrom to the intermediate transfer belt (5). A part of a first contact region (4S) between the intermediate transfer belt (5) and the photoconductor drum (4), and a part of a second contact region (1S) between the intermediate transfer belt (5) and the primary transfer roller (31), are made to overlap with each other. A summit of the primary transfer roller (31), closest to the photoconductor drum (4) in a direction in which the photoconductor drum (4) and the primary transfer roller (31) are aligned across the intermediate transfer belt (5), is set to intrude on the photoconductor drum (4), via the intermediate transfer belt (5). An intrusion amount (Kr) of the summit of the primary transfer roller (31) on the photoconductor drum (4), relative to an overlapping amount, is set within a predetermined proper range.
