Abstract: An image forming apparatus for forming an image on a pressure-deformable or pressure-damageable image receiving member, such as corrugated cardboard, using a photosensitive, pressure-sensitive recording medium referred to as a microcapsule sheet which has a surface coated with an immense number of microcapsules encapsulating a chromogenic material therein. The microcapsule sheet is exposed to imaging light to form a latent image thereon. A developing agent is deposited on the latent image formed portion of the recording medium and a pressure is applied thereto to develop a visible image. The visible image is formed on the microcapsule or another member. In a thermal transfer section, the imaged microcapsule sheet and the image receiving member which are superposed one on the other are heated to transfer the image onto the surface of the image receiving member.

Abstract: A developer material coating apparatus for electrostatically coating developer material on each of various kinds of support members having different thicknesses and surface conditions under various environmental conditions such as temperature and humidity in a developer material coating region to form a developer sheet, comprising a support member feeding unit for feeding each of the support members to the developer material coating region at a feeding speed while carrying the support member thereon, a developer material coating unit for triboelectrically charging the developer material while carrying the charged developer material thereon, and electrostatically supplying the charged developer material therefrom to the support member through a gap between the feeding unit and the coating unit to thereby form a developer sheet, and a control unit for controlling an amount of the developer material to be coated on the support member so that the developer material coated on the support member has a predetermined

Abstract: In a developer depositing unit for an image forming apparatus, a developer is supplied to a developer carrying roller by a supply roller. The developer is charged by the frictional charge produced by contact between the supply roller and the developer carrying roller. The charged developer is displaced from the developer carrying roller to an ordinary sheet of paper, as the sheet of paper is passed around an electrode roller, to be thus electrostatically deposited on a sheet. A ground conductive brush is positioned to contact both the supply roller and the developer carrying roller to remove any excessive built-up charge on the supply roller and the developer carrying roller. The brush also prevents a build-up of developer on both rollers that could result in their becoming clogged.

Abstract: A developer material coating apparatus comprising a developer material coating unit for triboelectrically charging the developer material and electrostatically supplying the charged developer material to the support member in the developer material coating region, the developer material coating unit including a carry roller rotatable around a rotational axis thereof for carrying thereon and feeding the charged developer material to the developer material coating region, and a support member feeding unit for feeding the support member to the developer material coating region while carrying the support member thereon, the support member feeding unit having a coating plane in the developer material coating region on which the support member is disposed so as to be electrostatically coated with the developer material and a guide unit for feeding the support member along the coating plane in a predetermined feeding direction, and wherein the carry roller is disposed at a predetermined interval away from the coatin

Abstract: A developer material coating apparatus for electrostatically coating developer material on a support member in a developer material coating region to form a developer sheet, comprising a counter electrode roller for feeding the support member through the developer material coating region while carrying the support member thereof, a carry roller for triboelectrically charging the developer material and electrostatically supplying the charged developer material to the support member disposed in the developer material coating region, at least one array of electrodes arranged along the inner surface of the counter electrode roller and a control unit for selectively supplying said electrodes with a voltage having an opposite polarity to that of the charged developer material to thereby coat the developer material on a desired portion of the support member.
