A photoconductor with a charge transport layer having about 20-25% by weight of 4-N,N-bis(4-methylphenyl)-amino-benzaldehyde-N′,N′-diphenylhydrazone is in an essentially standard resin binder, such as a polycarbonate resin binder. Electrical characteristics are those of the larger amounts using conventional charge transport agents, and the larger amount of binder provides much improved wear resistance and consequently longer useful life of the photoconductor. Charge transport layers with only the foregoing bis-methyl material do exhibit moderate fatigue upon exposure to light.

No antioxidant is required for electrical stability improvement.
