A process for preparing an imaging member includes applying an organic layer to an imaging member substrate, treating the organic layer and/or a backside of the substrate with a corona discharge effluent, and applying an overcoating layer to the organic layer and/or an anticurl backing layer to the backside of the substrate.

Enhancing adhesion of organic electrostatographic imaging member overcoat and anticurl backing layers

An electrophotographic imaging member including a supporting substrate, an optional charge blocking layer, an optional adhesive layer, a charge generating layer, and a charge transporting element including two sequentially deposited charge transport layers each including a hole transport material and an optional film forming binder. A first charge transport layer exhibits a first charge carrier transit time and second charge transport layer exhibits a second charge carrier transit time. The two charge transport layers are formed in one of two ways. First, each layer can be formed from a different charge transport material so that the charge mobility of the charge transport material of the first charge transport layer is about 4 to about 20 times lower than the charge mobility of the charge transport material of the second charge transport layer. Or, alternatively, each charge transport layer can be made using a different amount of the same charge transport material. In this case, the first charge transport layer includes of an amount of charge transport material that is about 5% to about 30% less than an amount of charge transport material used to form the second charge transport layer. In either case, the resulting electrophotographic imaging member exhibits a discharge surface potential at a light exposure greater than about 3 erg/cm , at a post exposure delay between about 20 milliseconds and about 500 milliseconds that can be raised from about 20 to about 200 volts above a discharge potential of an imaging member having the same components as the imaging member of the present invention except having only a single charge transport layer with a thickness that is equivalent to the charge transporting element of the present invention.

A crosslinkable charge transport layer material for a photoconductor includes at least one poly(arylene ether alcohol), at least one polyisocyanate crosslinking agent and at least one charge transport material dispersed in a solvent. The crosslinkable charge transport layer material is crosslinked following application of the coating solution to the photoconductor. The photoconductor including such crosslinked charge transport layer exhibits excellent wear resistance so as to have long life, thereby reducing the cost of electrophotographic printing machines employing such photoconductors therein.
