Abstract
Disclosed is a single-layer type electrophotosensitive material which comprises a conductive substrate, and a photosensitive layer made of a binder resin containing at least an electric charge generating material and an electric charge transferring material formed on said conductive substrate, wherein said photosensitive layer contains a polyalkylene glycol compound represented by the formula [1]:A1—O—[(CH2)m—O]n—A2wherein A1 and A2 are the same or different and represent an alkyl or aryl group having 1 to 50 carbon atoms, or a group: —CO—R10 (R10 represents an alkyl or aryl group having 1 to 50 carbon atoms), m represents an integer of 1 to 5, and n represents an integer of 2 to 100, which is superior in wear resistance, sensitivity and gas resistance.
