摘要： The toner includes a binder resin; a colorant; and a release agent. The first inter-particle force Fp(A) of the toner, which is measured under an environmental condition of 23° C. and 60% RH after the toner is pressed for 1 minute at 25° C. under a compression stress of 15 kg/cm2, is from 1.0×10−9 (N) to 1.0×10−6 (N). The difference (Fp(B)−Fp(A)) between the second inter-particle force Fp(B) of the toner, which is measured under the environmental condition of 23° C. and 60% RH after the toner is pressed for 1 minute at 50° C. under a compression stress of 15 kg/cm2, and the first inter-particle force Fp(A) is 0 (N) to 1.0×10−7 (N).

摘要： A fixing device includes a fixing rotator rotatable in a rotation direction, a heat source to heat the fixing rotator, a pressure rotator contacting the fixing rotator, a nip formation pad to form a fixing nip between the fixing rotator and the pressure rotator, a slide sheet, and an adhesive part. The slide sheet between the fixing rotator and the nip formation pad contacts an inner circumferential face of the fixing rotator. The slide sheet has a center part and both end parts in an axial direction orthogonal to the rotation direction. The adhesive part bonds the slide sheet to the nip formation pad. The adhesive part includes a first adhesive part on the center part and a second adhesive part on one of the end parts. The first adhesive part has a first area, and the second adhesive part has a second area smaller than the first area.

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.

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.
