摘要： A fixing device includes a rotator, a secured member, a pressure rotator, and lubricant. The rotator has flexibility and a sleeve form. The rotator includes an inner portion having a sliding surface. The inner portion has an elastic power of 55% or more. The secured member is disposed inside a loop of the rotator and has a slide surface on which the sliding surface of the rotator slides. The slide surface has a larger hardness than a hardness of the sliding surface of the rotator. The pressure rotator presses the rotator against the secured member and forms a nip between the rotator and the pressure rotator. The lubricant is provided between the rotator and the secured member.

The rotator includes an inner portion having a sliding surface. The inner portion has an elastic power of 55% or more. The secured member is disposed inside a loop of the rotator and has a slide surface on which the sliding surface of the rotator is to slide. The slide surface has a smaller surface roughness in a sliding direction of the rotator than a surface roughness of the sliding surface in the sliding direction of the rotator. The pressure rotator presses the rotator against the secured member and forms a nip between the rotator and the pressure rotator. The lubricant is provided between the rotator and the secured member.

摘要： A belt device includes a heater and a belt. The heater includes a substrate and a heat generator on the substrate. The heater has a first heater surface and a second heater surface opposite the first heater surface. The first heater surface is adjacent to the heat generator. The belt is rotatable, has an endless shape, and slides on the second heater surface. The belt includes an inner portion having an inner circumferential surface to slide on the second heater surface. The inner portion has an elastic power of 52% or more.

摘要： A belt device includes a belt, a secured member, a pressure rotator, and lubricant. The belt is rotatable and has an endless shape. The belt includes an inner portion having an inner circumferential surface. The inner portion has an elastic power of 55% or more. The inner circumferential surface of the belt slides on the secured member. The pressure rotator includes a porous elastic body and presses the secured member via the belt to form a nip between the belt and the pressure rotator. The lubricant is interposed between the inner circumferential surface of the belt and the secured member.

The belt has an inner portion having an elastic power of 55% or more and a sliding surface sliding on the slide surface of the secured member. The sliding surface has a surface roughness smaller than a surface roughness of the slide surface of the secured member. The pressure rotator presses the secured member via the belt to form a nip between the belt and the pressure rotator. The lubricant is interposed between the sliding surface of the belt and the slide surface of the secured member.

摘要： A pressing device includes a rotator, a secured member, a pressure rotator, and lubricant. The rotator has flexibility and a sleeve form and includes an inner portion having a sliding surface. The inner portion has an elastic power of 55% or more. The secured member is inside a loop of the rotator and has a slide surface on which the sliding surface of the rotator is to slide. The slide surface has a smaller surface roughness than a surface roughness of the sliding surface. The pressure rotator presses the rotator against the secured member and forms a nip between the rotator and the pressure rotator. The lubricant between the rotator and the secured member has a consistency of 275 or less.
