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： An image forming apparatus is constituted by an image-bearing member for bearing a latent image, and a developing apparatus for developing the latent image. The developing apparatus is constituted by a developer container for containing a toner, and a developer-carrying member for carrying and conveying the toner contained in the developer container to a developing zone opposite the image-bearing member. The developer-carrying member is provided with a coating layer containing electroconductive fine particles. A developer suitable for use in the above developing apparatus is given by a toner, which comprises a binder resin composition which contains 10 - 70 wt. % of a THF (tetrahydrofuran)-insoluble content and the remainder of a THF-soluble content including a component with a molecular weight of 10000 or below on a GPC (gel permeation chromatography) chromatogram of the THF-soluble content constituting 10 - 50 wt. % of the binder resin.

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.
