This paper is a review of our recent works on phthalocyanine pigment dispersed in dielectric resin and double layered photoreceptors for electrophotography. The photo-induced discharge curves of phthalocyanine-polymer photoreceptors have been known to exhibit an induction effect which is associated with a trapping of photocarriers at the surface of pigment. Electron acceptor was found to decrease this effect and consequently increase the photosensitivity. The energy level and density of traps are discussed from the results of thermally stimulated current and the values of drift mobility and life time were obtained by the measurement of time of flight method for phthalocyanine-polymer photoreceptor. The photoconductivity of evaporated thin film of metal-free phthalocyanine and the electrophotographic properties of double layered photoreceptor are discussed. The saturated surface potential decreased with increasing of the thickness and deposition rate of evaporated phthalocyanine layer. The application of phthalocyanine-polymer layer to platemaking was discribed. Electrophotographic printing plates consisting of a photoconductive layer and an alkali soluble photopolymer layer has a excellent photosensitivity, a high resolution and a long-run capability suitable for the projection and laser platemaking.
