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 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 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.

摘要： A heating device includes an endless rotator that rotates in a rotation direction. A heater contacts the endless rotator. An elastic body is disposed opposite an inner circumferential surface of the endless rotator and disposed downstream from the heater in the rotation direction of the endless rotator. A holder holds the heater and the elastic body. A pressure rotator is disposed opposite the heater and the elastic body via the endless rotator to form a nip between the endless rotator and the pressure rotator. A slide sheet covers a surface of the elastic body. The slide sheet includes an upstream end in the rotation direction of the endless rotator. The upstream end is sandwiched between the heater and the elastic body and between the elastic body and the holder. The upstream end is secured to the holder.

摘要： A heater includes a base and at least one resistive heat generator mounted on a face of the base. At least one electrode supplies power to the at least one resistive heat generator. A conductor couples the at least one electrode with the at least one resistive heat generator. A slide layer covers the at least one resistive heat generator and the conductor. The slide layer includes a projecting portion that defines a surface of the slide layer. The projecting portion is defined by a film thickness of at least one of the conductor and the at least one resistive heat generator. The projecting portion includes an upstream projection disposed opposite a lateral end of the base in a longitudinal direction of the base and a downstream projection disposed downstream from the upstream projection in a rotation direction of an endless belt that slides over the heater.

摘要： A heater includes a first heat generator and a second heat generator each of which has a hypothetical center line that divides each of the first heat generator and the second heat generator into a first section and a second section. A first conductor connects a first electrode to the first heat generator and the second heat generator. A second conductor connects a second electrode to the first heat generator and the second heat generator. A first primary connector connects the first conductor to the first section of the first heat generator. A second primary connector connects the first conductor to the second section of the second heat generator. A first secondary connector connects the second conductor to the first heat generator. A second secondary connector connects the second conductor to the second heat generator.
