摘要:
An image forming apparatus which has a plurality of image forming stations arranged in parallel, each of the image forming stations having a photosensitive drum, and which forms a desired image by combining toner images formed on the photosensitive drums. A laser scanning optical system deflects and scans a plurality of laser beams concurrently with a single polygon mirror to irradiate the photosensitive drums. In a monochromatic mode, the rotation speed of the photosensitive drum for forming a black image is changed higher, and synchronization of writing in a main scanning direction is performed by using one of the laser beams irradiating the other photosensitive drums of which rotation speeds are not changed.

摘要:
A master electric charge retaining medium 2 having electrostatic charge information recorded thereon is disposed face-to-face with a reproductive electric charge retaining medium 3, and a voltage is applied between the respective electrodes of the two electric charge retaining media to induce an electric discharge, thereby inversely reproducing the electrostatic charge information on the reproductive electric charge retaining medium, as shown in FIG. 2(b). It is possible to effect the reproduction any number of times while preventing the lowering in the contrast of the master electric charge retaining medium by making the electrostatic capacity of the master electric charge retaining medium adequately larger than the electrostatic capacity of the reproductive electric charge retaining medium. In addition, a master electric charge retaining medium 2 having an insulating layer with a relatively high softening point and a reproductive electric charge retaining medium 4 having a thermosoftening resin layer 4a are disposed face-to-face with each other to induce electric charge on the thermosoftening resin layer in correspondence to the electrostatic charge image on the master electric charge retaining medium 2, and the thermosoftening resin layer is softened by heating to form a dimple pattern thereon, thereby enabling transfer development to be effected any number of times without leaking the electrostatic charge.
摘要:
The present invention relates to an electrostatic information recording medium in which a charge retaining layer having high insulating properties is laminated on an electrode, and an electrostatic information recording/reproducing process wherein, while said electrostatic information recording medium is positioned in opposition to a photosensitive member on which a photoconductive layer is laminated, the recording medium is subjected to information exposure with the application of voltage between both electrodes to accumulate electrostatic charges thereon depending upon the dosage of said information exposure, and the electrostatic information thus accumulated is reproduced by potential reading. The present electrostatic information recording medium has an information density as expressed in terms of a high recording capacity of the order of 8.times.10.sup.8 bits/cm.sup.2, and makes it possible to process information in a planar state so that analog or digital information such as characters, line pictures, images, (0.multidot.1) information and sounds can be accumulated in the form of electrostatic charges. With the present electrostatic information recording medium, it is possible to obtain information of high quality and resolving power because of the information being accumulatable in electrostatic charge units. Due to its high charge retainability, it is further possible to store information permanently. Still further, it is possible to make inexpensive and simple recording/reproducing systems, since information can be output by reading local potentials of electrostatic latent images at any time and any scanning density.

The electrostatic information recording medium of the present invention has an electric charge retaining layer 11 stacked on at least an electrode layer 13, as shown in FIG. 1 . The electric charge retaining layer is formed from either 1 resin selected from among fluorocarbon resins and polystyrene resins, and an insulating organic substance having no photoconductivity. The electrostatic information recording medium may be produced, as shown in FIG. 5 , by stacking an insulating resin layer 10 on an electrode layer 13, stacking a photoconductive or electrically conductive fine particle layer 11 on the insulating resin layer 10, and further stacking an insulating resin layer 12 on the fine particle layer 11 to a thickness of 0.1 .mu.m to 1 .mu.m. The electrostatic information recording medium is superior in electric charge retaining characteristics, particularly in the performance of retaining positive information electric charge, and also excellent in heat resistance and moisture resistance. If the insulating resin layers 10 and 12 are formed by coating using a fluorocarbon resin solution, the electrostatic information recording medium can be produced with excellent processability.
