Patent number: 6665514Abstract: A fixing apparatus includes a fixing device which fixes a developer image onto a transferred body, by passing the transferred body, between a first roller and a second roller. A cleaning member, provided in contact with the first roller, removes the developer image adhered onto the first roller at the time of fixing the developer image. A feeding device feeds the cleaning member by a predetermined amount to change a contact position thereof to the first roller. A counter counts the number of pixels of the image. A control device operates the feeding device to feed the cleaning member on the basis of the number of pixels counted by the counter.Type: GrantFiled: May 30, 2002Date of Patent: December 16, 2003Assignees: Kabushiki Kaisha Toshiba, Toshiba Tec Kabushiki KaishaInventor: Yasunari Miyazaki
