Charge carrier mobility and mechanical properties of organic charge transport layers (CTLs) for xerography have been investigated. The CTLs were based on molecularly doped polycarbonate (PC) of different chemical structure (PC-A and PC-Z) and molecular mass. Low weight organic photoconductors (OPCs), in particular, DEH and phenyl-4-tolyl-2-naphthylamine (PTNA) were used as a dopant.In the CTLs, it was found out that the hole drift mobility tends to decrease as the molecular mass of the PC-A increases from 3x104 to (1.0-1.3)x105. In particular, a two fold and ten fold decrease in mobility was observed for the PC/PTNA and PC/DEH layers, respectively.Indentation hardness, density and durability of the CTLs were studied and some structural characteristics of the CTL components were also calculated. The structure and composition of the CTLs were shown to influence slightly on the mechanical properties of the layers under study. Characteristics of the xerographic drums layered with the CTL are presented and discussed.
