Abstract

An image forming apparatus includes: a pair of rollers for conveying paper; a rocking mechanism for rocking the pair of rollers in a second direction orthogonal to a first direction, the first direction being a paper conveying direction; an upstream pair of rollers provided upstream of the pair of rollers in the paper conveying direction for conveying the paper; an upstream rocking mechanism corresponding to the upstream pair of rollers for rocking the upstream pair of rollers in the second direction; a first paper detector for detecting an end position of the paper in the second direction; and a controller controlling the rocking mechanism based on the paper end position to effect first rocking correction in which the pair of rollers is rocked, wherein the controller controls the upstream rocking mechanism to effect second rocking correction in which only the upstream pair of rollers is rocked.
