Abstract
In an image forming apparatus, residual toner on an image bearing body is prevented from falling on a convey belt which conveys a recording medium. The convey belt is shifted in a direction perpendicular to a convey direction in which the recording medium is conveyed. A cleaning blade for removing residual toner from the image bearing body has a width that is larger than the range in which the convey belt is movable in the direction perpendicular to the convey direction. No cleaning device is required for the convey belt.
