Electrophotographic photoreceptor with two layer charge transfer layer, and apparatus utilizing the same

摘要

An electrophotographic photoreceptor including a charge generating layer and a charge transfer layer accumulated on a support member, the charge transfer layer including at least two layers of a support side layer and a surface side layer, wherein the support side layer contains A mol/cm3 of charge mol/cm3 of charge transfer material having a dipolar moment of not more than 0.75 and inorganic particles having a number average primary particle diameter of 3-150 nm, wherein A and B satisfies relations of (1) and (2), <?in-line-formulae description="In-line Formulae" end="lead"?>9.0x10-4>A>3.0x10-4 (1)<?in-line-formulae description="In-line Formulae" end="tail"?> <?in-line-formulae description="In-line Formulae" end="lead"?>8.0x10-4>B>2.0x10-5 (2).<?in-line-formulae description="In-line Formulae" end="tail"?>
