    摘要： Disclosed is an image forming apparatus including a first member having a surface endlessly moving in a specific direction a second member having a surface endlessly moving in the specific direction at a region facing the surface of the first member, and a supporting member holding the second member and to move together with the second member. The supporting member includes a release mechanism to release an engagement of the supporting member from the second member. A pressing member is included to press the second member via the supporting member to cause the second member to contact the first member under pressure to form a nip between the first and second members. The release mechanism releases the engagement of the supporting member from the second member when the second member is pushed away by a leading edge of a recording medium having a thickness greater than a reference thickness value.

    摘要： A recording apparatus for recording data in a thermosensitive recording medium. The recording medium has a reversible thermosensitive recording material capable of selectively assuming one of two visible states, e.g., a cloudy state and a transparent state or a colored state and a decolored state when heated. The thermosensitive material is applied to a sheet of resin. The apparatus surely erases data written in the medium with no regard to the time elapsed and the number of times that data has been repetitively written. The cloud density or the color density is prevented from changing with no regard to the storage temperature, the time elapsed, or the number of times of writing, thereby preventing image quality from being degraded. In addition, the medium has a long service life.

    摘要： An image transfer device provided in an image forming apparatus in which, employing an endless belt as an intermediate transfer member, image transfer is performed at nip positions of a primary transfer portion and secondary transfer portion. Generation of warp in the transferred image resulting from transmission of fluctuations in load and torque of the endless belt generated at the nip position of one transfer portion nip to the nip position of the other transfer portion is prevented. The endless belt is turned between rollers and the endless belt is individually driven at the primary transfer portion and secondary transfer portion by drive sources to generate deflection between the primary transfer portion and the secondary transfer portion.

    摘要： An image forming apparatus includes an image carrier for bearing a visible image thereon, an endless transfer-fixing belt stretchedly disposed between a plurality of spanning members, a pressure member for pressing the transfer-fixing belt to the image carrier while contacting a backside of the transfer-fixing belt at the transfer nip, and a heater for heating the visible image. The visible image on the image carrier is transferred onto the front surface of the transfer-fixing belt at the transfer nip and is transported to the transfer-fixing nip while heated by the heater, where the visible image is transferred and fixed on a recording member. The transfer-fixing belt is stretchedly arranged such that the transfer-fixing belt travels in a direction substantially perpendicular to a pressure direction of the pressure member in the proximity of the transfer nip.
