    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 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, 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 so that if one passage is clogged, the other can be used to discharge recording mediums. A switching means selects, 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.

    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. An image carrier gear for driving an image carrier is driven by a driving means gear at an image carrier driving position and transmits driving force to conveying force transmitting gear at a transfer driving position. The conveying force transmitting gear transmits conveying force to the transfer member. A time during which the image carrier moves from a latent image forming position to a transferring position is made substantially equal to a time during which the image carrier gear moves from an image carrier driving position to a transfer driving position.
