FIXING DEVICE, IMAGE FORMING APPARATUS, AND BELT

摘要

PROBLEM TO BE SOLVED: To make a belt move smoothly and convey a recording medium smoothly. SOLUTION: The fusing device has the belt, a pressure member, and a pushing member 13 disposed inside the belt and pushing the belt. If the friction coefficient of the inner circumferential surface of the belt is set to μi, the friction coefficient of a transit area for a recording medium on an outer circumferential surface of the belt is μ01, and where a friction coefficient of a non-transit area for the recording medium on the outer circumferential surface of the belt, having a friction coefficient rendered larger than the friction coefficient μ01, is μ02, the relation μ01< μi<μ02is satisfied. Therefore, even if a recording medium, having a small friction coefficient, is used or if the pressure member having mold-releasing property is used, the running power for making the belt run and conveyance force for conveying the recording medium can be increased.
