ABSTRACT:
An electrophotographic photosensitive member is constituted by an electroconductive support and a photosensitive layer disposed on the electroconductive support. The photosensitive layer contains a specific disazo pigment having a 2,2'-bis-1,3-benzdithiolene-diyl skeleton or a thiophene-diyl skeleton. The photosensitive member is effective for providing a process cartridge and an electrophotographic apparatus respectively including the photosensitive member with an excellent photosensitivity and a stable electric potential in repetitive use.
