A tubular member formed of a polyamide resin layer includes carbon black and a semi-aromatic polyamide resin having at least a repeating unit structure derived from an aromatic dicarboxylic compound and an aliphatic diamine compound with the alkyl carbon number in the range of from 9 to 13.

Tubular member, tubular member unit, intermediate transfer member, and image forming apparatus

A tubular article includes a layer containing a polyimide resin, a fluorinated polyimide resin and fluorine resin particles as an outermost layer.

Tubular article, tubular article unit, intermediate transfer material, and image forming apparatus

The invention provides an annular body having a resin layer. The resin layer has a resin and particles. The particles are at least one of conductive or magnetic. A surface of the resin layer has a first region and a second region. The first region is different from the second region in at least one of the surface resistivity or the magnetic flux density. The second region has a resin region and a high density region. The resin region is provided at an outer side with respect to the high density region in the thickness direction of the resin layer and is substantially free of the particle. The high density region has a higher content of the particles comparing to the resin region and the first region. The invention further provides a cartridge having the annular body. The invention further provides an image forming apparatus having the annular body.

Endless belt, cartridge, and image forming apparatus

The invention provides an annular body provided at an image forming apparatus, the annular body has at least an outermost periphery layer and an innermost periphery layer, each of which comprise carbon black, and a content of carbon black contained per unit of volume of the outermost periphery layer being smaller than a content of carbon black contained per unit of volume of the innermost periphery layer. The invention further provides an annular body stretching device, having at least the annular body and a plurality of annular body stretching units rotatably stretching the annular body at an inner surface of the annular body. The invention further provides an image forming apparatus having at least an image holder, a charging device, an exposing device, a developing device, a first transferring device, a second transferring device, and a fixing device, in which the intermediate transfer belt is the annular body.

Annular body, annular body stretching device and image forming apparatus

This invention provides a circular body, which is used for an image forming apparatus employing an electrophotographic system, the circular body containing: at least an inner layer containing resin and an outer layer that is laminated on an outer circumferential surface side of the inner layer and contains resin; and, as a conductive agent, polyaniline in the outer layer and carbon black in the inner layer; and satisfying the following relational expressions (1) and (2):13.0&#x2266;C1&#x2266;15.0&#x2003;&#x2003;(1)21.5&#x2266;C2&#x2266;25.0&#x2003;&#x2003;(2),wherein Crepresents the content (parts by weight) of the polyaniline with respect to 100 parts by weight of the resin forming the outer layer, and Crepresents the content (parts by weight) of the carbon black with respect to 100 parts by weight of the resin forming the inner layer, as well as a circular body unit using the circular body and an image forming apparatus using the circular body.

Circular body, circular body unit, and image forming apparatus

An image forming apparatus belt includes a belt main body; a guiding member that is fixed to the belt main body along at least a side edge on one side of the belt main body; and a detected portion for position detection that is provided in a slit of the guiding member.

Image forming apparatus belt having a detecting portion for position detection

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.

Circulating body and fixing device

The present invention relates to a sliding member for an electrophotographic apparatus using a non-porous sheet having a sliding surface including at least a fluorocarbon resin as a sheet-like member interposed between a press member A and a resin film tubular body. The invention also relates to an image fixing device using the sliding member.
