<p>An inverse dual-layer organic photoconductor (10) comprising a charge generation layer (CGL) (12) formed on top of a charge transport layer (CTL) (14), in turn formed on a substrate (16) such as a web (drum) or subbing layer, is disclosed, in which the CGL (12) includes a flexible polymer having a glass transition temperature (Tg) of less than about 120 DEG C as the binder for a charge generation species and in which the CTL (14) includes a rigid polymer having a Tg of greater than about 120 DEG C as the binder for a charge transport species. The CTL (14) is coated onto the substrate (16), using a non-chlorinated solvent. The CGL (12) is coated onto the CTL (14), also using a non-chlorinated solvent, under conditions so as to form a diffused region (24) at the boundary (22) of the CGL (12) and CTL (14). This type of photoconductor (10) yields extremely low noise, exceptionally high-speed and excellent stable charging/discharging performance in the xerography process at room temperature and elevated temperature. <MATH></p> |
