Abstract
An excellent electrographic photosensitive member having a high sensitivity, a high chargeability and a low residual potential. The electrographic photosensitive member comprises a photosensitive layer, or a photosensitive layer and an underlayer superimposed over an electroconductive support, wherein the photosensitive layer and/or the underlayer contain a chlorogallium phthalocyanine which is substituted with an electron-withdrawing group and has the following formula: ##STR1## where X represents an electron-withdrawing group such as a halogen atom and n is an integer of 2 to 4.
