Substrate with recessed surface portion

1. A coating method for a photoreceptor comprising:

(a) providing a single piece substrate including a deposition region and an optional uncoated region, wherein the deposition region includes a level intermediate region disposed between a first end region and a second end region,

wherein the first end region includes a first recessed surface portion which is a feature of the single piece substrate that increases the surface area of the first end region, wherein the first recessed surface portion is recessed below the level intermediate region;

(b) dip coating a layer of a coating solution over the first end region, the intermediate region, and the second end region in the recited sequence wherein the dip coated layer comprises materials for a photoreceptor layer; and

(c) drying the dip coated layer to result in the photoreceptor layer, wherein the photoreceptor layer is part of the photoreceptor.

2. The method of claim 1 , wherein the substrate is a cylinder.

3. The method of claim 1 , wherein the first recessed surface portion includes at least one groove.

4. The method of claim 1 , wherein the first recessed surface portion includes a tapered surface.

5. The method of claim 1 , wherein the first recessed surface portion includes a stepped area.

6. The method of claim 1 , wherein the dip coated layer comprises a charge transport material.

7. The method of claim 1 , wherein the portion of the dip coated layer over the first end region is substantially level.
