摘要： Capacitors 32 connected to their corresponding matrix-shaped picture elements 33 are connected to an image forming unit 20 on which an electrostatic latent image is formed. Switching elements 31 are also connected to the image forming unit 20. When the switching elements 31 are made conductive, their corresponding capacitors 32 are charged from a power source arranged outside, and a potential appears in each of their corresponding picture elements 33. Therefore, the electrostatic latent image can be more stably formed on these matrix-shaped picture elements over a time period which is determined by time constant. AS the result, electrostatic latent image formation can be achieved without using any ozone-generating pre-charger. In addition, the electrostatic latent image forming unit can keep its toner holding force even after the developing process to enable an image to be more reliably and clearly reproduced.

摘要： An apparatus for printing an image which is stored on an optical disk is read by a scanner. A plurality of images read out from the optical disk are edited to form an abstract image on the basis of a predetermined unit (e.g., one page), and code data (i.e., retrieval data) is added to the abstract image. The resultant image, including both the abstract image and the code data, is printed on a sheet. The code data is extracted from the printed image, and desired images are retrieved from the optical disk on the basis of the code data.

摘要： 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.
