Abstract:
There is provided an electrophotographic photosensitive member, a process cartridge and an electrophotographic apparatus in which residual potential is suppressed and a ghost image is prevented from being generated in a low-humidity environment in an undercoat layer of the electrophotographic photosensitive member. An electrophotographic photosensitive member including: an undercoat layer containing a strontium titanate particle having a maximum peak at a position of 2θ=32.20±0.20 (θ represents a Bragg angle) in a CuKα characteristic X-ray diffraction pattern and a half-value width of the maximum peak of 0.10 deg or more and 0.50 deg or less, and a titanium oxide particle; and a photosensitive layer containing a polyvinyl butyral resin, and a process cartridge and an electrophotographic apparatus each provided with the electrophotographic photosensitive member.

Claim (Index 1):
An electrophotographic photosensitive member comprising: a support; an undercoat layer; and a photosensitive layer in the mentioned order, wherein\n the undercoat layer comprises a binder resin, a titanium oxide particle and a strontium titanate particle, the strontium titanate particle has a maximum peak at a position of 2\u03b8=32.20\u00b10.20 (\u03b8 represents a Bragg angle) in a CuK\u03b1 characteristic X-ray diffraction pattern, a half-value width of the maximum peak is 0.10 deg or more and 0.50 deg or less, and the photosensitive layer comprises a polyvinyl butyral resin.
