Abstract
An image forming apparatus includes: a primary transfer section which transfers a toner image formed in an image forming section onto an intermediate transfer belt; a back-up roller arranged on an inner periphery side of the intermediate transfer belt; a secondary transfer roller that is in pressure contact with the back-up roller through the intermediate transfer belt and transfers the toner image from the intermediate transfer belt onto a transfer material while conveying the transfer material; a moving mechanism which moves a position where the secondary transfer roller is in contact with the back-up roller through the intermediate transfer belt; and a controller which controls the moving mechanism based on information relating to a thickness of the transfer material obtained by a thickness information obtaining section.
Claims19
An image forming apparatus comprising:
- (a) an image forming section which forms a toner image on a photoreceptor;
- (b) a primary transfer section which transfers the toner image formed in the image forming section onto an intermediate transfer belt;
- (c) a back-up roller arranged on an inner periphery side of the intermediate transfer belt;
- (d) a secondary transfer roller that is in pressure contact with the back-up roller through the intermediate transfer belt and transfers the toner image from the intermediate transfer belt onto a transfer material while conveying the transfer material;
- (e) a thickness information obtaining section which obtains information relating to a thickness of the transfer material;
- (f) a moving mechanism which moves a position where the secondary transfer roller is in contact with the back-up roller through the intermediate transfer belt;
- and
- (g) a controller which controls the moving mechanism based on the information relating to the thickness of the transfer material obtained by the thickness information obtaining section.
