PURPOSE:To form a distinct image without having the image memory of a black negative by making light quantity to be radiated on an image carrier more than four fold of the half exposure of the image carrier. CONSTITUTION:A photosensitive body 2 is obtained by coating in order of a charge generating layer 21 and a charge carrying layer 22 on an aluminum cylinder which is cut on the both sides; and as far as the part where some leftover toner (b) after transferring and gathered is concerned, the toner (b) becomes a filter, so that an under-exposure is caused on that part toward the photosensitive body 2, then image becomes faulty because the memory is caused. And also if a laser exposure is less than four fold of the half exposure quantity of the photosensitive body 2, the memory is caused and the distinct image can not be obtained however the weight concentration of the toner is changed. But in the case of more than four fold light quantity, the filter effect of the leftover toner after transferring is prevented. The distinct image without having the image memory of black negative can be formed by this. |
