Patent ID: 8114563

Claim:
A method of preparing an electrophotographic photoreceptor comprising: an electroconductive substrate, a photosensitive layer located overlying the electroconductive substrate, and a crosslinked surface layer located overlying the photosensitive layer, comprising: a tri- or more functional radical polymerizable monomer having no charge transport structure; and a radical polymerizable compound having a charge transport structure, wherein the crosslinked surface layer has a surface roughness (Ra) not greater than 0.2 μm and a peel strength not less than 0.2 N/mm, the method comprising: performing two or more oscillation spray coatings, and hardening the coatings with heat or optical energy to form the crosslinked surface layer, wherein a droplet diameter (D50) of the first spray coating is not less than 7 μm and that of the second or subsequent spray coating is less than 7 μm, and wherein D50 is an average of half cumulative curve of 100 droplet diameter distributions when measured at an interval of 0.1 sec of sprayed droplets.
