Claims

[Scope of utility model registration request]

(1) When a support bearing an unfixed toner image is passed between a pair of fixing rollers, one of the fixing rollers that fixes the donor image to the support by heating or pressure is in contact with the toner image. In a fixing roller cleaning device, the toner adhering to the surface of the fixing roller is wiped off by a cleaning member pressed against the roller, and the cleaning device is composed of two adjacent cleaning members, one on the front and the other, one of which is attached to the surface of the fixing roller. In the cleaning section on the front side in the rotational direction, the leading edge of the pressure contact surface between the material and the surface of the fixing roller is located at least on the intrusion side of the support rather than directly above the center of the roller, and the cleaning section is located on the rear side than the width of the cleaning member. A fixing roller cleaning device characterized in that the width of the member is wider than that of the member.

(2) The fixing roller cleaning device according to claim 1, wherein the cleaning member on the front side in the roller rotation direction of the two cleaning members is impregnated with an anti-offset liquid. (3) The entire cleaning device is supported movably in the direction of the generatrix of the circumferential surface of the fixing roller, and the cleaning device is moved in conjunction with a power source that drives the fixing roller to cause the cleaning device to reciprocate on the surface of the roller. A cleaning device for a fixing roller according to claim 1, characterized in that the cleaning device wipes the surface of the fixing roller.
