PURPOSE:To obtain picture images having same quality as an initial picture image even after it is used repeatedly for a continuous reproduction by distributing a specified compd. to at least the surface of the member. CONSTITUTION:A compd. expressed by the formula I is distributed to at least the surface of a member for imparting triboelectric charge electricity. In the formula I, each R1 and R2 is an H atom, lower alkyl group, etc.; M is Zn or Co, etc.; n is a valency of M. The member is prepd. by coating a liquid prepd. by dispersing the compd. in a solvent such as acetone, etc., in a dispersion medium or in a resin, and drying the coated film, or by molding a resin contg. the compd. dispersed therein, as it is. Thus, a member for imparting triboelectric charge which provides a picture image having almost same picture quality as good as the quality of an initial picture image even after a continuous copy, is obtd. |
