PURPOSE:To obtain a carrier generating material capable of generating carriers on exposure to the visible light and having superior film forming performance by reacting a rhodanine derivative having a reactive substituent with the side chains of a chain polymer to be used as a carrier generating material and combining said derivative with said side chains. CONSTITUTION:The rhodanine derivative represented by general formula I combined with the side chains of the chain polymer having reactive substituents is used for the polymer of the carrier generating material to be used for an electrophotographic sensitive body and the like. In formula I, R1 is lower alkyl, optionally substituted aryl, or OH. Said carrier generating polymer is prepared by reacting the reactive substituents formed on the side chains of the chain polymer with the rhodanine derivative having the reactive substituent represented by structural formula II in which B is the reactive substituent, and C is a divalent organic group, and R1 is optionally substituted aryl, H or OH, and p is 0 or 1, thus permitting the obtained carrier generating material to generate carriers by exposure to the visible light and have superior film forming performance. |
