Abstract

PURPOSE:To obtain a highly sensitive receptor having flat sensitivity all over the visible region by forming a charge generating layer contg. a specified disazo pigment and a charge transferring layer contg. a specified hydrazone compound on an electrically conductive support. CONSTITUTION:A prescribed amount of a disazo pigment represented by formula Iis dissolved in THF, and a prescribed amount of a hydrazone compound represented by formula II (where R is H, 1-4C alkyl, 1-4C alkoxy, dialkylamino, halogen, nitro or OH, and n is an integer of 1-5) is dissolved in THF separately from the pigment. The former soln. contg. the pigment of formulaIis applied to an electrically conductive support 11 of Al or the like to form a charge generating layer 22 having 0.01-5mum thickness, and the latter soln. contg. the hydrazone of formula II is applied to the layer 22 to form a charge transferring layer 33 having 2-10mum thickness. Thus, an electrophotographic receptor is obtd.
