Abstract

A photoreceptor drum is disclosed with a charge transport layer comprising a substituted terphenyl diamine having the structure of Formula (1): wherein R 1 and R 2 are independently selected from the group consisting of hydrogen, alkyl having from 1 to 10 carbon atoms, halogen, and phenyl; and wherein at least one of R 1 and R 2 is not hydrogen.

Description

technical field [0001] The present disclosure relates generally, in various exemplary embodiments, to electrophotographic imaging elements, and more particularly to photoreceptor drums having charge transport layers comprising substituted terphenylenediamines. Background technique A photoreceptor generally includes a carrier substrate, a charge generation layer, and a charge transport layer ("CTL"). For example, in a negatively charged system, a photoconductive imaging element may include a support substrate, a conductive layer, an optional charge blocking layer, an optional adhesive layer, a charge generating layer, a charge transporting layer, and an optional protective or outer layer. coating. In particular, the carrier substrate is in the form of a rotating drum. The charge transport layer generally includes at least charge transport molecules ("CTMs") dissolved in a polymeric base resin, the layer is substantially non-absorbing in the spectral region of the inte...
