An electrophotographic photosensitive member is constituted by disposing a photosensitive layer on a support. The photosensitive layer contains oxytitanium phthalocyanine and a specific disazo pigment of the formula (I) or (II) each characterized by having particular coupler residues. The photosensitive layer may preferably include a charge generation layer and a charge transport layer. The charge generation layer may preferably include a first charge generation layer containing the above disazo pigment of the formula (I) or (II) and a second charge generation layer containing the above oxytitanium phthalocyanine. The electrophotographic photosensitive member including the photosensitive layer described above is usable for providing an apparatus unit and an electrophotographic apparatus showing excellent electrophotographic characteristics such as high photosensitivity, good potential stability in repetitive use and good image-forming properties substantially providing no black spots.
