A resin belt for an image forming apparatus includes a resin base layer containing a filler. The exposed area of the filler on an inner circumferential surface side of the resin base layer is 0.1% or less.

Resin belt for image forming apparatus, fixing belt, fixing device, and image forming apparatus

A unit includes: a developing device configured to develop an electrostatic charge image that is formed on a surface of an image carrier, as a toner image with a developer including a brilliant toner containing a flat brilliant pigment, the developer being accommodated in the developing device; and a fixing device configured to fix the toner image onto a surface of a recording medium at a fixing temperature of 130&#xb0; C. or higher and 230&#xb0; C. or lower that includes a fixing belt, a first roller and a second roller that are disposed inside the fixing belt and support the fixing belt while applying tension to the fixing belt, and a pressure roller, the first roller and the pressure roller sandwiching the fixing belt to form a nip portion.

An endless belt includes a metal substrate, and a heat-resistant resin layer that is disposed as an innermost layer on an inner peripheral surface of the metal substrate and that contains a resin and a thermally conductive filler having an aspect ratio of 20 or more. In the heat-resistant resin layer, an orientation ratio of the thermally conductive filler with respect to a circumferential direction of the endless belt is 20% or more.

Endless belt, fixing device, and image forming apparatus

Provided is a fixing device including a rotatable rotating member, a tubular member that is movable while coming into contact with the rotating member, a pressure member that is arranged inside the tubular member and nips a recording medium holding an unfixed toner image at a nip portion formed between the rotating member and the tubular member by bringing the tubular member into pressure contact with the rotating member, to apply pressure for fixing the unfixed toner image on the recording medium, and a holding member that holds the pressure member, wherein the pressure member is made of an elastomer, and the end position of one surface of the elastomer that comes into contact with the tubular member is located further toward the upstream side in the transport direction of the recording medium than the end position of the other surface of the elastomer held by the holding member.

Fixing device, and image forming apparatus

A belt pressurizing device includes: an endless belt that is circularly driven; a pressing member that presses the endless belt against a facing member with the endless belt interposed between the pressing member and the facing member; and a lubricant supplying member that supplies lubricant to reduce sliding resistance of the endless belt pressed by the pressing member, so as not to be in contact with the endless belt.

Belt pressurizing device and image forming apparatus

A fixing device includes: a fixing member that fixes a toner image on a recording medium; a fixing pressure member that forms, between the fixing member and the fixing pressure member, a fixing pressure portion for the recording medium holding an unfixed toner image to pass through, by being brought into pressure contact with an outer circumferential surface of the fixing member; a drive unit that rotates the fixing pressure member by rotating the fixing member; and a lubricant adjusting member that comes into contact with an inner circumferential surface of a belt member, at least either the fixing member or the fixing pressure member being the belt member. The lubricant adjusting member is separated from the inner circumferential surface of the belt member, at least while the recording medium and the belt member are in contact with each other and while rotation of the belt member is stopped.

Fixing device, image forming apparatus and method of controlling fixing device

The present invention provides a fixing device that has a planar member including a heat conduction layer. The heat conduction layer has a predetermined thickness and relatively pressed against a rotary member being rotated so that the device fixes an unfixed toner image born by a recording sheet onto the recording sheet by causing the sheet bearing the unfixed toner image to pass between the planar member and the rotary member and applying heat and pressure to the unfixed toner image. The device includes a heater that applies heat to the unfixed toner image born by the sheet passing between the planar member and rotary member. The heat conduction layer includes a heat conduction anisotropic material whose heat conduction coefficient showing the degree of easiness of heat conduction in a surface direction in which the heat conduction layer extends is larger than that in a thickness direction.

Fixing device, sheet member, and image forming apparatus

A circulating body driven with its surface being circulated along a fixed route and having a base material provided with a tubular outside peripheral surface and a surface layer covering the outside peripheral surface of the base material, the surface static friction coefficient of the surface layer is designed to be 0.06 or less with common paper at 100&#xb0; C.
