PURPOSE:To obtain remarkable sensitization effect by incorporating a slight amt. of 3,5-dinitrobenzoic acid sensitizer in a polyvinylcarbazole (PVK)-perylene type pigment dispersion system. CONSTITUTION:A perylene type electrostatic charge generating pigment is dispersed into a charge transfer medium composed essentially of a PVK type resin, and this combined medium incorporates 3,5-dinitrobenzoic acid in an amt. of 0.1-10, preferably, 1-4pts.wt. per 100pts.wt. PVK type resin. |
