Abstract: Fixing belt is brought into pressure-contact with the surface of fixing roller such that fixing belt rotates according to rotation of fixing roller, thereby forming, between fixing belt and fixing roller, fixing nip portion through which recording sheets pass. A pressing area of an opposing surface of pressing member contacting the surface of fixing roller via fixing belt is smaller in each end portion of the opposing surface in the axis direction of fixing roller than in a central portion of the opposing surface in the axis direction of fixing roller. This makes speed of conveying recording sheets faster in each edge portion in the width direction perpendicular to a recording sheet conveyance direction than in a central portion in the width direction. Thus, creases of recording sheets can be prevented while a recording sheet passes through fixing nip portion between fixing roller and fixing belt mutually brought into pressure-contact.

Abstract: A fixing device slide member has a surface 40a of a sheet body 40, which surface is made of heat-resistant resin. A specific wear rate on the surface 40a of the sheet body 40 in the ring-on-disc test is 10×10?8 mm3/(N×m) or less on condition that a counterpart material is aluminum, roughness Ra is equal to 0.2 micrometer, PV is equal to 51.2 MPa×m/min, and measuring time is 50 hours. Thus, the surface 40a of the sheet body 40 is enhanced in wear resistance so as to be free from generation of worn powder, which suppresses torque increase in a pressurizing belt caused by the worn powder.
