摘要： A positively-charged electrophotographic organic photoreceptor includes an electrically conductive support, and a charge transport layer and a charge generating layer sequentially stacked on the electrically conductive support. The charge generating layer is formed by coating a charge generating layer forming composition that includes a fluorene compound, a charge generating material, a binder resin and an organic solvent on the charge transport layer, and drying. The organic photoreceptor has high sensitivity, while suppressing contamination of a charge generating layer during coating, and thicknesses of a charge transport layer and a charge generating layer may be adjusted. Also, the electrostatic properties of the organic photoreceptor, including charge potential and exposure potential, may be easily adjusted. The organic photoreceptor may be applied to an electrophotographic development system using a liquid toner having a small particle size and a high retained charge amount with an increased surface charge amount of the organic photoreceptor.
摘要翻译：带正电的电子照相有机感光体包括导电性支持体，以及依次层叠在导电性载体上的电荷输送层和电荷产生层。电荷产生层通过在电荷输送层上涂布含有芴化合物，电荷产生材料，粘合剂树脂和有机溶剂的电荷产生层形成组合物并干燥而形成。有机感光体具有高灵敏度，同时抑制涂布期间电荷产生层的污染，并且可以调节电荷传输层和电荷产生层的厚度。此外，可以容易地调节包括电荷电位和曝光电位的有机感光体的静电特性。可以使用具有小的粒径和高保留电荷量的液体调色剂将有机感光体施加到电子照相显影系统上，同时具有增加的有机感光体的表面电荷量。

摘要： A double-layered positively-charged organic photoreceptor t does not suffer from contamination caused by charge transport compounds that dissolve out during coating of a charge generating layer, and in which the charge generating layer and a charge transport layer have suitable interfacial properties for effective charge transfer. The composition that forms a charge transport layer on an electroconductive support contains a first charge transport compound that is soluble in an acetate solvent, a second charge transport compound that is insoluble in an acetate solvent, a binder resin, and an organic solvent. The method of manufacturing the photoreceptor includes: coating a surface of an electroconductive support with the charge transport layer forming composition and drying the surface to form a charge transport layer; and coating a surface of the charge transport layer with a charge generating layer forming composition and drying the surface to form a charge generating layer.
