The light-transmitting electrode is arranged in correspondence with a pixel, and the photoconductive element and the capacitor element which are arranged on one surface of the light-transmitting electrode and connected in series with each other through the light-transmitting electrode are arranged on a substrate. The plurality of photoelectric converters each of which can apply a voltage across the corresponding photoconductive and capacitor elements are two-dimentionally arranged, and the photoconductive elements and the capacitor elements are commonly connected to each other. A voltage is applied across the photoconductive elements and the capacitor elements.

Electrostatic latent image forming apparatus having a plurality of

Without using corona charge, a predetermined voltage is applied to all of the island-like electrodes provided on a front surface of an electrostatic latent image forming member, which is then exposed by exposing device from a rear surface thereof. Consequently, a contrast potential is generated between the island-like electrodes two-dimensionally arranged, thereby forming an electrostatic latent image. By setting the exposing light-emitting diode array inside the electrostatic latent image forming member, the light irradiating position and the developed position can be made close to each other. Therefore, the latent image can be developed by toner at the maximum contrast potential of the electrostatic latent image on the image forming member. The toner image is then transferred and fixed on an image formation medium.

Image forming device

An image sensor according to one aspect of the present invention comprises a plurality of linearly arranged line sensors each including a plurality of linearly arranged picture elements acting as photodetecting elements, wherein the photodetecting elements positioned at the ends of the linear arrangement are smaller in width in the direction of the linear arrangement than the photodetecting elements positioned in the central portion.
