Abstract
An image forming apparatus includes a charging device, an image bearing member, an electrostatic image forming device, a development device including a developer bearing member, a transfer device, and a controller. The controller controls a potential of the image bearing member such that, during image formation to form an image on a recording material having a predetermined size, an absolute potential value (V) of a region on a surface of the image bearing member outside a region corresponding to a passage region for a recording material in a width direction orthogonal to a movement direction of the surface of the image bearing member, an absolute potential value (V) of a non-image portion in the region corresponding to the passage region for the recording material, and an absolute potential value (Vdc) of the developer bearing member satisfy the following condition:Vdc<V1<V2.
