Abstract

PURPOSE:To obtan 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 divinylbenzene compound on an electrically conductive support. CONSTITUTION:A photosensitive layer 44 is formed on an electrically conductive support 11 by laminating a charge generating layer 22 having 0.01-5mum thickness and contg. 10-100wt% trisazo pigment represented by formulaI, and a charge transferring layer 33 having 2-100mm thickness and consisting of 10- 80wt% divinylbenzene compound represented by formula II (where R is carbazolyl, pyridyl, thienyl, indolyl, furyl, optionally substituted phenyl, styryl, naphthyl or anthryl; and the substituent is dialkylamino, alkyl, alkoxy, halogen, aralkylamino or amino) and a binder resin such as polyester resin. 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.
