JPS57204046A - Electrophotographic receptor - Google Patents

Abstract

PURPOSE:To obtain the titled receptor with high sensitivity to a semiconductor laser by forming a photosensitive layer consisting of a charge generating layer contg. a trisazo pigment and a charge transferring layer contg. a specified anthracene compound on an electrically conductive support. CONSTITUTION:A photosensitive layer 2 is formed on an electrically conductive support 1 by laminating a charge generating layer 21 having 0.01-5mum thickness and contg. 10-100wt% trisazo pigment represented by formulaI, and a charge transferring layer 22 having 2-100mum thickness and consisting of 10-80wt% anthracene compound represented by formula II (where R1 is H or halogen; R2 is H, 1-4C alkyl, 1-4C alkoxy, dialkylamino or optionally substituted diaralkylamino; and R3 is H, alkyl or halogen) and a binder resin such as polyester resin or contg. further additives such as halogenated paraffin. The resulting receptor with high sensitivity shows flat sensitivity over the whole visible range and the wavelength range of a semiconductor laser, has superior durability, and gives a clear image.
