PURPOSE:To enhance the dispersability of the pigment in the compsn. by using a polymer contg. an acidic functional group as a binder resin. CONSTITUTION:This compsn. is the compsn. used for forming a photosensitive body or photoconductive toner and is formed by incorporating at least the photoconductive pigment (e.g. zinc oxide) and the binder resin consisting of the polymer contg. the acidic functional group (A). A (co)polymer which consists of (meth)acrylate, vinyl acetate, etc., as a starting raw material and has an ester bond, OH group, sulfonic acid group, etc., is usable as the component A. Then, the dispersibility of the pigment is enhanced and, therefore, the electrostatic chargeability and sensitivity of the compsn. are improved. |
