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 diarylmethane compound on an electrically conductive support. CONSTITUTION:A prescribed amount of a disazo pigment represented by formulaIis dissolved in THF, and a prescribed amount of a compound represented by formula II (where R1 is 1-11C alkyl, phenyl or heterocyclic, each of R2 and R3 is H, 1-4C alkyl, hydroxyalkyl, alkoxy-substituted alkyl or aralkyl, and R4 is H, 1-4C alkyl, alkoxy or halogen) 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, and the latter soln. contg. the compound of formula II is applied to the layer 22 to form a charge transferring layer 33.
