Abstract
An image forming apparatus includes a controller that performs one or more times a first image forming process including performing image formation on a sheet medium, and conveying the sheet medium in a conveyance direction by rotating a first roller by a first number of rotations and rotating a second roller disposed downstream of the first roller in the conveyance direction by a second number of rotations smaller than the first number of rotations. When a count of times the first image forming process has been performed becomes a particular number of times, the controller performs a second image forming process including performing image formation on the sheet medium, and conveying the sheet medium by rotating the first roller by a third number of rotations smaller than the first number of rotations and rotating the second roller by the second number of rotations.
