摘要： This invention provides an organic photoconductor which does not experience end-seal wear in normal use. This invention provides charge transport formulation that is easily prepared and coated by standard, dip-coating methods. This is realized by addition of a small amount of poly(methyl methacrylate-co-ethylene glycol dimethacrylate). Commercially available, 8μ spherical particles are used. These microspheres are insoluble in common organic solvents, but are readily dispersed into polycarbonate-based charge transport formulations. A photoconductor roller is mounted in pressure engagement with two end seals, each on opposite side of the roller.
