摘要： An image forming apparatus includes a belt-shaped image carrier adapted to support a toner image: a transfer roller; a contact/separation mechanism, operable to bring the transfer roller into contact with the image carrier to transfer the toner image from the image carrier onto a recording medium and operable to separate the transfer roller from the image carrier after the toner image is transferred onto the recording medium; and a rotation applier, operable to apply a first rotation to the transfer roller in a state that the transfer roller is separated from the image carrier. The rotation applier and the transfer roller are mechanically separated from each other when the transfer roller is in contact with the image carrier. When the contact/separation mechanism brings the transfer roller into contact with the image carrier, a circumferential speed of the transfer roller is made coincident with a circumferential speed of the image carrier.

摘要： A charge roller includes a core, a resistive layer disposed on a circumferential surface of the core to charge an image-bearing member without contact, and gap members formed of tape-shaped films. These films are fixed to both ends of the charge roller by winding each of the films in a direction opposite a rotational direction of the charge roller in use and perpendicular to the axial direction thereof to form n layers (wherein n≧2) extending in the axial direction at every position in the circumferential direction of the charge roller. The gap members are pressed against a circumferential surface of an image-bearing member to define a charge gap between the image-bearing member and the charge roller.

摘要： A stainless steel separator, which is good of corrosion-resistance and low of contact-resistance, is proposed for a fuel cell. Its surface faced to a fuel electrode is pickled, which the other surface faced to an oxidizing electrode is roughened by electrolytic etching or the like. The roughening treatment may be performed before or after pickling and passivation. The roughened surface of the stainless steel separator without pickling or passivation may be faced to the oxidizing electrode.

摘要： Writing electrodes of a writing device are kept in contact with a latent image carrier with a small pressing force by a weak restoring force of a substrate. An electrostatic latent image is written on the latent image carrier by applying or removing charge relative to the latent image carrier which is already uniformly charged by a charge control device. The application or removal of charge is conducted via charge-transfer between the latent image carrier and the writing electrodes which are in contact with each other. The electrostatic latent image is developed by a developing device to form a developing powder image and this developing powder image is transferred to a receiving medium such as a paper by a transferring device. Since the writing electrodes are employed as the writing device, the apparatus can be manufactured smaller and simply and can steadily write an image.
