Abstract:
1. An electrophotographic photosensitive member, comprising: a cylindrical support; a conductive layer comprising a binder material and a metal oxide particle formed on the cylindrical support; and a photosensitive layer formed on the conductive layer, wherein the metal oxide particle is a titanium oxide particle coated with tin oxide doped with phosphorus; when an absolute value of a maximum current amount flowing through the conductive layer in a case of performing a test of continuously applying a voltage of −1.0 kV comprising only a DC voltage to the conductive layer is defined as Ia [μA], and an absolute value of a current amount flowing through the conductive layer in a case where a decrease ratio of a current amount per one minute flowing through the conductive layer reaches 1% or less for the first time is defined as Ib [μA], the Ia and the Ib satisfy the following relations (i) and (ii); and a volume resistivity of the conductive layer before the test is performed is from 1.0×10
