  • Publication number: 20100150627
    Abstract: A lubricant molded body, which is to be applied to a surface of a photosensitive layer for electrophotography in an image forming apparatus, for example, is composed of at least two kinds of higher fatty acid metallic salts having respectively different carbon numbers. As the higher fatty acid metallic salt that forms lubricant molded body, compounds such as zinc stearate, calcium stearate, barium stearate, aluminum stearate, zinc laurate, calcium laurate, etc. may be recited. The higher fatty acid metallic salts may contain at least one kind of fillers selected from the group consisting of silica, alumina, tungsten disulfide, molybdenum disulfide, graphite fluoride, graphite, boron nitride, polytetrafluoroethylene (PTFE), ethylene tetrafluoroethylene (ETFE), and polyvinylidene fluoride (PVDF).
