Abstract
An electrophotographic imaging member including a charge generating layer, a charge transport layer and an overcoating layer, the transport layer including a charge transporting aromatic diamine molecule in a polystyrene matrix and the overcoating layer including a hole transporting hydroxy arylamine compound having at least two hydroxy functional groups and a polyamide film forming binder capable of forming hydrogen bonds with the hydroxy functional groups of the hydroxy arylamine compound. This imaging member is utilized in an imaging process.
Claims12
An electrophotographic imaging member comprising a supporting substrate, a charge generating layer, a charge transport layer and an overcoating layer, said transport layer comprising a charge transporting molecule in a polystyrene matrix and said overcoating layer comprising a hole transporting hydroxy arylamine compound having at least two hydroxy functional groups and a polyamide film forming binder capable of forming hydrogen bonds with said hydroxy functional groups of said hydroxy arylamine compound.
An imaging process comprising providing an electrophotographic imaging member comprising a supporting substrate, a charge generating layer, a charge transport layer and an overcoating layer, said transport layer comprising a charge transporting molecule in a polystyrene matrix and said overcoating layer comprising a hole transporting hydroxy arylamine compound having at least two hydroxy functional groups and a polyamide film forming binder capable of forming hydrogen bonds with said hydroxy functional groups of said hydroxy arylamine compound, depositing a uniform electrostatic charge on said imaging member with a corona charging device, exposing said imaging member to activating radiation in image configuration to form an electrostatic latent image on said imaging member, developing said electrostatic latent image with electrostatically attractable toner particles to form a toner image, transferring said toner image to a receiving member and repeating said depositing, exposing, developing and transferring steps, the time elapsed between said exposing and the developing steps is between about 0.5 millisecond and about 500 milliseconds.
An electrophotographic imaging process according to claim according to claim 13 wherein the time elapsed between said exposing and the developing steps is between about 1 millisecond and about 200 milliseconds.
