An improved electrostatic image forming apparatus including a controller for controlling the supplied voltage on the grid electrode of the main charger which gives the charges on the photosensitive member. Voltage on the grid electrode is controlled so that the charged potential on the photosensitive member may be held virtually at zero potential after the completion of the image forming operation until the predetermined time.

Electrostatic image forming apparatus

A paper sheet feeding arrangement for feeding paper sheets one sheet by one sheet, including a paper sheet cassette, a paper feeding roller, a feed roller, a paper sheet separating roller rotated, in contact with the feed roller, in a direction counter to a paper feeding direction, a return roller provided rotatably and coaxially with one of the feed roller and the paper sheet separating roller, and a paper sheet returning device which, in response to release of the paper sheet cassette from a paper feeding section, not only brings the feed roller and the paper sheet separating roller out of contact with each other but rotates the return roller in the direction counter to the paper feeding direction.

Paper sheet feeding arrangement

An electrostatic recording apparatus including a plurality of recording electrodes arranged at right angles to a transport direction of an electrostatic recording paper, a plurality of first recording electrodes disposed at the upstream side of the recording electrodes and each having a first face confronting the electrostatic recording paper, and a plurality of second recording electrodes disposed at the downstream side of the recording electrodes and each having a second face confronting the electrostatic recording paper. In the apparatus, the width of the first face, measured in the transport direction of the electrostatic recording paper, is smaller than that of the second face.
