Electrophotographic image forming apparatus and process cartridge, and electrophotographic photoreceptor therefor

摘要

An image forming apparatus including at least an image irradiator configured to irradiate a photoreceptor with a coherent light beam while scanning to form pixel light spots thereon for forming an electrostatic latent image thereon, wherein the light spots overlap with adjacent light spots; and an image developer configured to develop the electrostatic latent image with a developer, wherein the photoreceptor comprises an intermediate layer located overlying an electroconductive substrate, a charge generation layer located overlying the intermediate layer and a charge transport layer located overlying the charge generation layer, wherein the charge generation layer satisfies the following relationship: T1<=3.5% wherein T1 represents a relative mirror reflectance of the charge generation layer against the coherent light beam when the coherent light beam irradiates the charge generation layer at an incident angle of 5°.
