A photoconductive imaging member includes a hole blocking layer, a photogenerating layer, a charge transport layer, and an optional overcoating layer, wherein at least one of the charge transport layer and the optional overcoating layer is formed in a sol-gel process.
摘要:
An electrophotographic photoreceptor is disclosed which is provided with a substrate with a coating with a metal oxide as an interface between the substrate and photoconductive layers. A process for applying the metal oxide layer to the substrate is also disclosed.
摘要:
A photoconductive imaging member comprised of a hole blocking layer, a photogenerating layer, and a charge transport layer, and wherein the hole blocking layer is generated from a solution of a metal alkyloxide, an amino alkylsilane, an aminoalkoxy silane or an aminoalkyl alkoxy silane, a polymer binder, and an organic solvent.
摘要:
A photoconductive imaging member including a hole blocking layer, a photogenerating layer, and a charge transport layer, and wherein the hole blocking layer contains, for example, a metal oxide; and a mixture of a phenolic compound and a phenolic resin, and wherein the phenolic compound can contain at least two phenolic groups.
摘要:
An electrographic or electrostatographic imaging member comprises a supporting substrate, an undercoating layer, a charge generating layer, and a charge transport layer. Thick undercoating layers were prepared with a charge erase enabler by doping an undercoating layer with a charge generating pigment that is strongly absorbing at typical erase lamp light. Doped thick undercoating layers demonstrate good electrical properties with an erase energy reduction of at least 50 V. A process for fabricating an imaging member and an apparatus comprising such an member are also disclosed.
