PURPOSE:To obtain a satisfactory sensitization effect by incorporating nitrophthalic acid in a combination of polyvinylcarbazole (PVK)-perylene type pigment. CONSTITUTION:A perylene type electrostatic charge generating pigment is dispersed into a charge transfer medium composed essentially of a PVK type resin, and this medium incorporates nitrophthalic acid represented by the formula shown here (n being 1 or 2) as a sensitizer, in an amt. of 0.1-10, preferably, 1-4pts.wt. per 100pts.wt. PVK type resin. |
