Abstract
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.
Claims8
A fixing apparatus comprising:
- a fixing device having a first roller and a second roller in pressure contact with the first roller, the fixing device fixing a developer image corresponding to an image onto a transferred medium by passing the transferred medium, onto which the developer image has been transferred, between the first roller and the second roller, in a direction in which the developer image contacts the first roller;
- a cleaning member which is in contact with the first roller, and removes the developer image adhered to the first roller at the time of fixing the developer image;
- a feeding device which feeds the cleaning member by a predetermined amount to change a contact position thereof to the first roller;
- a counter which counts the number of pixels of the image;
- and
- a control device which operates the feeding device to feed the cleaning member, on the basis of the number of pixels counted by the counter.

- a cleaning member which is in contact with the first roller, and removes the developer image adhered to the first roller at the time of fixing the developer image;
- a feeding device which feeds the cleaning member by a predetermined amount to change a contact position thereof to the first roller;
- a counter device which counts, by respective counters, the numbers of pixels of a plurality of regions, the regions being obtained by dividing a region of the image, whose number of pixels is to be counted, in an axial direction of the first roller;
- and
- a control device which operates the feeding device to feed the cleaning member, on the basis of counting of a predetermined number of pixels by any one of the counters of the counter device.
