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 fluorene compound on an electrically conductive support. CONSTITUTION:A prescribed amount of a disazo pigment represented by formula Iis dissolved in THF, and a compound represented by formula II[where R1 is H, halogen, cyano, 1-4C alkoxy or 1-4C alkyl, and Ar is a group of formula III or IV (where R2 is 1-4C alkyl, R3 is H, halogen, 1-4C alkyl or the like, m is 1 or 2, and each of R4 and R5 is H, 1-4C alkyl or the like)]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. |
