PURPOSE: An electro-photographic photosensitive unit, a process cartridge, and an electro-photographic apparatus are provided to obtain the superior quality of output images by reducing the number of positive ghost images. CONSTITUTION: An electro-photographic photosensitive unit includes a conductive support, an intermediate layer, and a photosensitive layer. The intermediate layer and the photosensitive layer are successively formed on the conductive support. The intermediate layer includes a polyolefin resin and an organic electron transporting material. The polyolefin resin includes a polyolefin resin including repeating units, represented by chemical formulas 11, 21, and 22. The organic electron transporting material includes a compound selected from a group including an imide-based compound, a benzimidazole-based compound, a quinine-based compound, a cyclopentadienylidene-based compound, an azo-based compound, and the derive of the same. |
