摘要:
An image reproducing apparatus of the type in which a toner image formed on a charge receptor is transferred to a transfer member and is fixed on said transfer member by the application of pressure and heat by use of an intermediate transfer belt. An auxiliary pressure contact roller is disposed so as to come into contact, via the intermediate transfer belt, with a support roller forming a transfer-fixing portion, disposed inside the intermediate transfer belt and opposing a pressure contact roller via the intermediate transfer belt, so that the contact area between the support roller and the intermediate transfer belt is enlarged.
摘要:
A method and apparatus for transferring and fixing toner image wherein a toner image is transferred and fixed onto a transfer material from a toner image retainer through an intermediate transfer member. The toner image on the intermediate transfer member is heated at a temperature lower than the toner fusion temperature, and the transfer material is heated to the toner fusion temperature or over. A pressing unit to press the transfer material onto the intermediate transfer member is heated at the toner fusion temperature or over.
摘要:
The present invention is such that in a recording apparatus comprising a toner image carrier and an intermediate image transfer material which receives the toner image transferred from the image carrier and then transfers the toner image onto the subsequent transfer sheet material (recording sheet), and an image transfer section for transferring the toner image onto the moving transfer sheet material comprising a transfer roller and pressure roller pressing thereon, the recording apparatus has the following pre-heating means comprising a heat member and a pressing member which is located at a position prior to the transfer section and which, brings the subsequent transfer sheet material into close contact with or presses the subsequent transfer sheet material against the periphery of the pressure roller, the member being provided at least on its side facing the transfer sheet material with a heat-resistant, elastically deformable porous material.
摘要:
An intermediate transfer body for a transfer type recording apparatus which comprises a substrate consisting of a thermoplastic resin layer and a thermosetting resin layer, wherein said body further comprises an intermediate transfer layer can be added to the intermediate transfer body. The intermediate transfer body consists of an elastic material, such as a fluoro-carbon rubber or a silicone rubber.
摘要:
An electrostatic reproducing apparatus wherein a toner image formed on a toner image retaining member in the form of a belt is transferred to and fixed on a transfer material through an intermediate transfer member in the form of a roll. The intermediate transfer member is formed by providing a thin transfer layer on the outer periphery of a metal roll. The belt comprises an elastic material layer. A transfer pressure roller for pressing the back surface of the belt contacts with the intermediate transfer member, and the surface of the transfer pressure roll is covered with an elastic body.
摘要:
A recording apparatus having an image carrier and a heated intermediate transfer member is disclosed. The improvement is the addition of a shielding member of porous metal for preventing water vapor and/or heat from reaching the surface of the image carrier, wherein the shielding member has a trapping capability for condensing and trapping the water vapor.
摘要:
A recording apparatus wherein an electrostatic latent image on an electrostatic latent image retaining member is developed into a visible image by means of a developer transported on the surface of a developer carrier having at least a magnet movably provided therein. At least a part of the electrostatic latent image retaining member is constituted by a magnetic material.
摘要:
A cleaning member for an intermediate transfer member of a reproducing apparatus for transferring a toner image formed on a toner image forming member to the intermediate transfer member and further transferring the toner image to a subsequent transfer material from the intermediate transfer member, wherein the cleaning member has an outer layer of a porous or fibrous substrate and an outer surface of the toner, a resin identical with the toner or a resin compatible with the resin, or the cleaning member has an outer layer of adiabatic elastic material and a thin metallic outer surface layer.
摘要:
A recording apparatus for electrostatic images comprising a photoreceptor, an intermediate transfer substance and a means for heating toner images transferred onto said intermediate transfer substance and transferring again and fixing them onto a transfer material, characterized in that there are provided a means for detecting a temperature of aforesaid photoreceptor and a means for keeping the temperature of said photoreceptor within a fixed range of T.sub.1 through T.sub.2.
摘要:
In the transfer of a toner image from a transfer medium such as a belt to transfer material such as paper, heating and fixing of the toner is required. According to the present invention, two sources of heat are used, one applied to the transfer medium and the other to the paper, the heat applied to the transfer medium being insufficient to melt or fuse the toner, with the heat applied to the paper being greater than necessary for fusing. When the hot paper contacts the underheated transfer medium the temperature of the latter is then and only then increased to the fusing temperature and the transfer and fixing of the toner image upon the paper takes place.
