PURPOSE:To obtain an almost flat sensitivity over the whole visible range and the wavelength range of a semiconductor laser by using a laminate type receptor contg. combinedly a specified charge generating substance and a specified charge transferring substance. CONSTITUTION:An electrically conductive support such as a metallic plate, a platic film having a thin metallic layer, or paper or a plastic film coated or impregnated with an electrically conductive substance is coated with a dispersion prepared by dispersing a trisazo pigment represented by formulaIand a binder resin in a solvent to form a charge generating layer 21. The layer 21 is coated with a soln. prepared by dissolving a hydrazone compound represented by formula II (where R is alkyl or benzyl, and Ar is naphthalene, styryl or the like) and a binder resin in a solvent such as THF to form a charge transferring layer. Polyester, polybutyral, ethylcellulose or the like is used as the binder resin of the charge generating layer, and polycarbonate, polystyrene, polyurethane or the like is used as the binder resin of the charge transferring layer. |
