The present invention provides: a single-layer-type electrophotographic photoreceptor for positive electrification which, even when exposed to ozone, is stable and decreases little in initial electrification characteristics, while retaining the electrical properties, and which is reduced in initial memory images; an image-forming device equipped with the photoreceptor, the device giving images with a satisfactory density; and a cartridge. The present invention relates to a single-layer-type electrophotographic photoreceptor for positive electrification which comprises an electroconductive support and, formed thereover, a photosensitive layer comprising a binder resin, a charge generation material, a hole transport material, and an electron transport material in the same layer, and which is characterized in that the electron transport material is a compound represented by formula (1) and the photosensitive layer contains an aromatic compound represented by formula (7) and having a molecular weight of 180-400. |
