Abstract

The invention relates to an electrophotographic photoreceptor, a process cartridge and an image forming apparatus, and aims to provide an electrophotographic photoreceptor having an outermost surface with high mechanical strength and can restrain thickness nonuniform and image ghost for long. The electrophotographic photoreceptor comprising: a conductive substrate; a photosensitive layer formed on the conductive substrate; and an outermost surface layer that is a layer made of a cured material of a composition including at least one compound represented by the following formula (I) and at least one compound having charge transportability and an azo group: wherein in formula (I), F represents an n-valent organic group having a hole transporting property, R represents a hydrogen atom or an alkyl group, L represents a divalent organic group, n represents an integer of 1 or more, and j represents 0 or 1.

Description

technical field The present invention relates to an electrophotographic photoreceptor, a process cartridge, and an image forming apparatus. Background technique Generally, an electrophotographic image forming apparatus has the following structure and steps. Specifically, the image-formed product is obtained by charging the surface of the electrophotographic photoreceptor with a charging unit to impart a desired polarity and potential to the surface; exposing the surface to light to selectively decharge the surface, thereby forming an electrostatic latent image on the surface; attaching toner to the latent image by a developing unit, thereby developing the latent image to form a toner image; The toner image is transferred onto an image-receiving medium by a transfer unit. In recent years, electrophotographic photoreceptors have been more frequently used in copiers, laser printers, and the like because of their advantages in providing high-speed and high-quality printing. ...
