摘要: A recording medium having a toner image formed thereon is moved to pass through a press contact portion between an endless belt being heated and an pressure roller pressed against the endless belt. When passing through the press contact portion, the toner image is fused and permanently affixed onto the recording medium. An oil application width O of an oil application roller is shorter than belt width B of the endless belt, and a maximum passing width P of a recording medium that may be supplied for the image formation, but is longer than a maximum image-forming width I within which an image may be formed on the recording medium.

摘要: The present invention provides an electrophotographic image forming apparatus capable of forming a high quality image by eliminating an expansion/contraction, displacement in color or nonuniformity of color of the image formed on a transfer member (7). An image carrier gear for driving an image carrier (1) is driven by a driving means gear (9) at an image carrier driving position (11a) and transmits driving force to conveying force transmitting gear (8) at a transfer driving position (11b). The conveying force transmitting gear (8) transmits conveying force to the transfer member (7). A time during which the image carrier (1) moves from a latent image forming position (1a) to a transferring position (1b) is equalized almost with a time during which the image carrier gear moves from an image carrier driving position to a transfer driving position.

摘要: An image forming apparatus which is able to form either single or double sided copies on a recording medium while achieving an excellent image quality in either a matted or glossy finish. The image forming apparatus includes a fixing portion (400) in which a first roller includes a first temperature and hardness for forming a matted image, whereas a second roller includes a higher temperature and hardness for forming a glossy image. Alternatively, or in addition, to different hardness and temperatures, the recording medium can be conveyed at a first speed to form a matted image, and a slower speed to form a glossy image. The image forming apparatus further includes an inverse and re-fixing sub-mode, which utilizes an inverting and returning passage (94) , for reducing the curl in a recording medium, and thus also reducing the instances in which clogging takes place. The inverting and returning passage has a length sufficient to accommodate a plurality of recording mediums. Moreover, the image forming apparatus is provided with first and second discharge passages (93a,93b) so that if one passage is clogged, the other can be used to discharge recording mediums. A switching means selects (510), based on detection sensors, through which discharge passage a recording medium is fed. The operations of the image forming apparatus are coordinated by a control unit (80).

摘要: A fixing apparatus including a heating member (201,207) and a pressurizing member (202) that are in contact with each other under pressure to define a nip through which a sheet (212) carrying an unfixed toner image is passed and a temperature sensor (208) for sensing the temperature of the heating member. The fixing apparatus further includes a temperature controller (213) for proportionally controlling an electric power supplied to the heating member, based on the sensed temperature supplied from the temperature sensor (208), and for controlling the tempereture of the heating member so that it is at a predetermined target temperature, and a heating condition changing device for changing a heating condition based on the target temperature and the sensed temperature when the temperature of the heating member is sensed. The electric power supplied to a halogen lamp functioning as a heat source (207) of the heating roller (201) is controlled in proportion to the temperature difference between the sensed temperature and the target temperature of the heating roller. The temperature of the pressurizing roller (202) is estimated from the sensed temperature of the heating roller (201) and the target temperature at a time when the sensing is performed. Then, heating conditions (such as the target temperature of the heating roller) which are suitable for the temperature of the pressurizing roller (202) are reset.
