Patent ID: 8467705

Claim:
An image forming apparatus, comprising: a development unit that forms a toner image according to image data; an intermediate transfer belt tightly stretched across a plurality of rollers so as to be able to move endlessly in a sub scanning direction upon image formation, and having an outer circumferential surface to which the toner image formed with the development unit is transferred; a secondary transfer opposing roller which is one of the plurality of rollers and across which the intermediate transfer belt is tightly stretched; a secondary transfer roller which comes into contact with the outer circumferential surface of the intermediate transfer belt at a portion where the intermediate transfer belt is tightly stretched across the secondary transfer opposing roller, and transfers the toner image on the intermediate transfer belt to recording paper; a movement mechanism that moves at least one of the plurality of rollers across which the intermediate transfer belt is tightly stretched, or the secondary transfer roller, and changing a pressed state of the intermediate transfer belt by the secondary transfer roller at a nip part of the secondary transfer opposing roller and the secondary transfer roller where the toner image is transferred from the intermediate transfer belt to the recording paper; a movement mechanism control unit that controls a travel distance of the roller to be moved by the movement mechanism; and a temperature detection unit that detects temperature of the intermediate transfer belt, wherein the movement mechanism control unit controls the travel distance of the roller according to the temperature detected with the temperature detection unit.
