摘要： An electrostatic recording apparatus includes a developing agent carrier member (15) arranged along a predetermined developing agent convey path. A developing agent conveying section (16) conveys a developing agent along a surface of the developing agent carrier member (15). A plurality of recording electrodes (EL) are arranged on the surface of the developing agent carrier member (15) at a predetermined pitch. An opposite electrode (5) is arranged to oppose the plurality of recording electrodes (EL) at a predetermined gap. A voltage applying section (18) applies a voltage corresponding to recording information to each of the plurality of recording electrodes (RL) to selectively transfer the developing agent, which is conveyed along the surface of the developing agent carrier member (15), to the opposite electrode (5). The developing agent carrier member (5) has a step at a portion on its surface shifted to an upstream side of a developing agent convey direction from a position closest to the opposite electrode (15). At least distal end portions of the plurality of recording electrodes (EL) project from this step toward the closest position to form projections. The projections are swingable in a direction of approaching or going away from the opposite electrode (5).

摘要： A developing sleeve (10) for a magnetic brush developing unit, which is provided with a plurality of axially parallel grooves (11) formed at a predetermined pitch in the circumferential direction on the surface thereof, is disclosed. Each of the grooves and the interfacing portion between each groove and its adjacent circumferential surface curve gradually and gently in section in the circumferential direction of the developing sleeve. The pitch for the formation of the grooves may be set to be equal to or larger than the difference in travel length between the surface of the developing sleeve and that of a photosensitive drum during the time required for a point on the photosensitive drum during the time required for a point on the photosentive drum to move along the full length of a developing area.

摘要： The photocopier uses a development process employing a magnetic brush formed on a rotating sleeve (102) of non-magnetic material in which a system of permanent magnets (108) rotates. The outer surface of the sleeve is subjected to a sandblasting process after grinding in order to create a very uniform finely roughened surface in order to make the thickness of the toner layer forming the magnetic brush constant. The photocopier also employs a toner fixing system operating cold and under pressure by means of a pair of rollers (56, 58) of different diameter rotating at the same angular speed in order to create slippage of the upper roller relative to the lower roller for the purpose of obtaining perfectly flat copies. The coppier also contains a single circuit board (80) for the low voltage and high voltage supply.

摘要： An apparatus (20) which develops a latent electrostatic image with magnetic particles (54). The apparatus (20) includes a member (62) having a multiplicity of magnetic fibres (66) extending outwardly therefrom. At least a portion of the fibres (66) have the free end regions thereof contacting the latent image. A magnet field attracts the particles (54) to the member (62). Relative movement between the member (62) and magnet field moves the particles (54) into contact with the latent image and moves the free ends of the fibres (68). As the particles (54) are deposited on the latent image, the end regions of the fibres (66) move forming a substantially uniform particle image.
