US 2019/0155202 A1 · IMAGE FORMING APPARATUS

Abstract

An image forming apparatus for forming an image on a recording material includes an image forming portion configured to form the image on the recording material; a fixing portion including a flexible cylindrical rotatable member and a roller configured to form a fixing nip, in which the recording material on which the image is formed is nipped and fed, in press-contact with the rotatable member and configured to fix the image on the recording material; an oblique movement detecting portion configured to detect oblique movement of the recording material; and a controller. When the oblique movement detecting portion detects the oblique movement of the recording material, the controller executes control for increasing a feeding interval of the recording material to the image forming portion.
