PURPOSE:To improve the durability against the generation of wear and flaws on the surface by rubbing by incorporating polyethylene (PE) powder subjected to a surface oxidation treatment into the surface layer. CONSTITUTION:This photosensitive body is formed by incorporating the PE powder subjected to the surface oxidation treatment into the surface layer. Since the PE powder subjected to the surface oxidation treatment is uniformly dispersed into the coated film, there is no need for adding a large amt. of a surfactant thereto and the generation of bubbles in the coating liquid is obviated. The content of the PE powder to be dispersed into the surface layer is adequately 1 to 50wt.%, more particularly preferably 1 to 30wt.% by the weight of the solid content (exclusive of the PE powder) of the surface layer. The images having a high grade are obtd. at all times without generating flaws and image flow even after the repetitive use in this way. The effect of reforming the surface layer is insufficient if the content is below 1%. The light transmittability is degraded and the flowability of the carrier is degraded as well if the content exceeds 50wt.%. |
