Abstract
A triphenylmethane polymer, a process for production thereof, and photoconductive compositions and a member containing the polymer are described; the polymer is represented by formula (I) ##STR1## wherein R is an alkyl group, X is H or a methyl group, Z is an alkylene group or a p-xylylene group, Y is H, a methyl group, a methoxy group, a tertiary amino group, halogen, a nitro group or a cyano group, Q is H or a methyl group, and n represents a polymerization degree sufficient to obtain the intrinsic viscosity [.eta.] of the polymer from 0.005 to 1.000.
