摘要： A toner image is formed on an electrophotograph photosensitive body by a developing means in which toner powder is stored. The toner image is transferred onto a transfer material and the image is outputted. The toner powder which remains on the electrophotograph photosensitive body after the transfer is recovered by the developing means which also functions as a cleaning means. The material of the surface of the electrophotograph photosensitive body is positive-chargeable organic photosensitive material which contains a phthalocyanine compound as a charge generating agent, a diphenoquinone compound as an electron transporting agent and a nitrogen-containing polyaromatic cyclic compound as a positive hole transporting agent. The toner powder has a sphericity which is calculated by dividing the area (Sc) of a circle whose diameter is the absolutely maximum length of the particles by the actual projection area (Sr) of the particles, within a range of 1.0-1.3 and is colored polymer particles produced by a suspension polymerization method.
