A lubricant solid contains, in a content of 92 mass % or more and 100 mass % or less, a lubricant having a polygonal network bond structure.

Lubricant solid, image forming apparatus, and process cartridge

A roll member includes a conductive elastic layer, and a surface layer provided on the conductive elastic layer. The surface layer contains a crosslinked product of crosslinkable nylon, the crosslinking degree of the surface layer specified by formula (1) below is 0.3 or more and 0.7 or less, and the thermal degradation index of the surface layer specified by formula (2) below is 2.1 or more and 2.3 or less.Crosslinking degree=absorbance at 1078 cm&#xf7;absorbance at 2935 cm&#x2003;&#x2003;Formula (1):Thermal degradation index=absorbance at 1638 cm&#xf7;absorbance at 1543 cm&#x2003;&#x2003; Formula (2):

Roll member, charging member, charging device, process cartridge, and image forming apparatus

A fixing belt includes an annular polyimide resin base layer having a lower imidization ratio in the outer peripheral surface than in a central portion in the thickness direction, a metal layer provided on the outer peripheral surface of the polyimide resin base layer, and an elastic layer provided on the outer peripheral surface of the metal layer.

Fixing belt, fixing device, and image forming apparatus

A fixing belt includes an annular resin base layer having a water absorption rate of 3% or less, a metal layer provided on the outer peripheral surface of the resin base layer, and an elastic layer provided on the outer peripheral surface of the metal layer.

An electrophotographic photoreceptor includes a conductive substrate; a charge generating layer provided on the conductive substrate; a charge transporting layer provided on the charge generating layer, which is configured to include a charge transporting material and a polycarbonate; and an outermost surface layer provided on the charge transporting layer, which is constituted with a cured film formed of a composition including a chain polymerizable compound having at least a charge transporting skeleton and a chain polymerizable functional group in the same molecule, and has an A value represented by the following equation (1) being from 0.1 to 0.3, and a B value represented by the following equation (2) being 0.02 or less, each of which is determined by an Attenuated total reflection Fourier transform infrared spectroscopy:=(1/13)&#x2212;(0/03)&#x2003;&#x2003;Equation (1)2/23&#x2003;&#x2003;Equation (2).

Electrophotographic photoreceptor, process cartridge, and image forming apparatus

An image forming apparatus includes an image carrier; a charger that electrically charges the image carrier; an image forming section that forms an electrostatic latent image on the image carrier and develops the electrostatic latent image; a transferring-fixing section that transfers the image from the image carrier and fix the image onto a recording medium; a cleaning member; and a cleaning member moving section. The cleaning member cleans an unnecessary substance adhering onto a surface of the image carrier by abutting against the surface of the image carrier, and is capable of moving between an abutment position and a separation position where the cleaning member is separated from the image carrier. The cleaning member moving section moves the cleaning member from the separation position to the abutment position in accordance with a surface resistance of the surface of the image carrier.
