摘要： PURPOSE:To prevent variation in image density during continuous image formation and to obtain an image of stable quality, by approximating the surface potential of a photoreceptor after the image forming process to the mean surface potential in the image forming process as much as possible. CONSTITUTION:The image forming process P is completed in steps I -VII, and repeated successively according to the necessary number of copies or completed once to enter a halt period. While a photoreceptor is rotated after the image forming process, the step I is utilized to remove an optical memory and an electrostatically charged memory, and a primary charger is operated in a step VIIIto hold the surface potential of the photoreceptor to 750V in the image forming process to the overall width and overall circumference or to approximate it to 750V as much as possible. Consequently, even when numbers of copies are taken successively, a decrease in image density with the number of taken copies is prevented.

摘要： PURPOSE:To eliminate the difference of density of an image due to the difference of the copying speed, by varying the irradiation of light of the pre-exposure in accordance with the copying speed and thus carrying out a control so as to ensure nearly a constant amount of free carrier within a photoreceptor when the photoreceptor is charged. CONSTITUTION:A pre-irradiating light source 25 is put between a cleaning means 11 and a primary charger 2 so as to irradiate the surface of a photosensitive drum 1. When carrying out the copying, the copy modes such as the equal size, reduction, magnification, etc. are selected by means of a copy mode changeover switch. The degree of light irradiation is set weak ad strong with a high and low speeds of copying respectively and synchronously with decision of the copying speed corresponding to the selected copy mode. In such way, the copying having an almost equal image density is obtained.

摘要： PURPOSE:To sort and mention a secret part and an open part and to copy selectively the open part only by forming a picture selectively only with regard to a specified color picture in an original picture. CONSTITUTION:Only a red information on a white paper having red and black informations is formed on a photosensitive body consisting of each conductive, insulating, a photoconductive and surface insulating layer 1-4. A picture is exposed on the photosensitive body at about the same time as a primary electrostatically charging, and red R and white W parts are polarized into the layer 3 by a light L. In a process (b), the picture is exposed through a red filter 7 at the same time as the opposite polarity or an AC electrostatically charging by an electrifier 6. In this case, the white W part disappears and the charge of the layer 3 and the layer 4 disappears. As for the R part, since an L2 is cut off by the filter 7 and not irradiated to the layer 3, the polarized charge of a process (a) is held, the charge of the layer 4 also remains, and this part is developed by a red toner. In case of other two colors, said operation can be executed in the same way by changing the filter 7.
