摘要： The equipment has a moving belt heater (1a,1b) for heating copy paper (6) transported at an arbitrary speed. The heater can move in the direction of transport of the paper and faces the paper. The gap between the heater and the paper can be set so that the air trapped between the two moves with the heater or the paper. The transport speed of heater and paper can be synchronised or can be independently controlled. The heater can be supported by a driven roller in which a heat source is provided

摘要： A heating belt is laid along a conveying path for a recording medium moved after development, a halogen lamp is incorporated in a belt drive roller for driving the heating belt so as to heat the heating belt by heat generated by the halogen lamp, and accordingly, the heating belt whose temperature is controlled at a predetermined temperature heats the recording sheet. With this arrangement, the conveying speed of the recording sheet and the moving speed of the heating belt are set to be equal to each other. Alternatively, the heating belt may itself generate heat.

摘要： The fixing device fixes an unfixed toner image (5) which is provided on a recording paper with a first and a second side. The device has two opposing heating and press rollers which define between them a press section. This holds the paper (3) such that the image on the paper (3) is heated and pressed to fix the image (5). The heating and press rollers are pressed towards each other over the press section. The device also has a paper advancing path with an entry side and an exit side relative to the press section. The paper (3) is conveyed through this path such that it is partially wound about the opposing rollers. The first side of the paper (3) is in contact with one of the rollers on the entry side of the advancing path. The second side of the paper (3) is in contact with the other roller on the exit side of the path.

摘要： The feed mechanism (100) holds the paper between rollers and moves it by friction. It can therefore be used whether or not the paper has a perforated edge. The system includes linear sensors (43, 44) which monitor the edge of the paper. They emit a signal to an electronic control operating a corrector unit (37-56). It adjusts the feed by oblique compensation, if necessary, to provide accurate presentation of the paper to the carrying section (412, 502, 504) where it meets the printing drum (402). Two edge-rollers (506) at each side of the paper maintain its exact position on the bearing roller (508) during and after printing. Precise and reliable registration of the print on the paper is thus ensured.

摘要： The arrangement includes a first and a second heating drum with a respective number of heaters with different heat production areas, whereby positions of divisions of the heat production areas between adjacent heaters in the first and in the second heating drum are displaced with respect to each other. The recording material is conveyed, while it is held between the first and the second heating drum which are pressed together.

摘要： A toner image heating device for heating a recording material holding a toner image includes: a first heating roller having a plurality of heaters which are different in heat generating region from one another; and a second heating roller having a plurality of heaters which are different in heat generating region from one another. A heat generating region dividing position between said heaters adjacent to each other in said second heating roller is shifted from a heat generating region dividing position between said heaters adjacent to each other in said first heating roller.

摘要： An image forming apparatus includes a feed roller mechanism disposed downstream of a transfer corotron 412 constituting a transfer section and composed of driven rollers 506 located on both edges of a continuous recording medium 100 which are outside an image transfer area and a drive roller 508 extending over the whole width of the continuous recording medium 100, so that when transferring a toner image from an image recording member 402, on which the toner image is to be formed, to the continuous recording medium 100, friction by the rollers achieves reliable conveyance against an attraction between the image recording member 402 and the continuous recording medium 100 without disturbing an unfixed image on the continuous recording medium 100. The image forming apparatus further includes a line sensor 43 for detecting a position where a reference edge of the recording medium is present, a line sensor output device which judges a position of the recording medium reference edge in cooperation with the line sensor to send a recording medium reference edge position signal or mask 61 adjustable in position for shielding a portion of a detection window of the line sensor, a recording medium position correction device 11 which finds a recording medium position correction value from an output of the line sensor for carrying out feedback control, and a guide 38 for preventing rising of the recording medium.
