Document Type and Number:
Japanese Patent JP5079153
Kind Code:
B1
Abstract:
Provided are an electrophotographic photosensitive member in which leakage doesn't easily occur, a process cartridge and an electrophotographic apparatus each including the electrophotographic photosensitive member, and a method of manufacturing the electrophotographic photosensitive member. The electrophotographic photosensitive member includes a conductive layer including titanium oxide particle coated with tin oxide doped with a hetero element. When an absolute value of a maximum current amount flowing through the conductive layer in a case of performing a test of applying −1.0 kV including DC voltage to the conductive layer is defined as Ia, 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 minute reaches 1% or less for the first time is defined as Ib, the relations of Ia≰6000 and 10≰Ib are satisfied. A volume resistivity of the conductive layer before the test is 1.0×108 Ω·cm to 5.0×1012 Ω·cm.
