摘要： In a fixing device, a heat roller and a fixing gear for rotating the heat roller are arranged concentrically, and coupled to each other by inserting a key formed in the fixing gear into a keyway formed in the heat roller. The keyway is designed such that the key is allowed to move along a direction in which the heat roller is rotated. For example, the keyway is formed by notching a free end of a one-side rotary shaft of the heat roller so as to extend along the direction in which the heat roller is rotated.

摘要： In a fixing unit, a fixing roller is rotated under driving force transmitted from a paper discharge unit-side gear of a driving section via a fixing roller driving gear, and holds and conveys a recording medium in cooperation with a pressure roller in a nip region. When a control section determines that acceleration conditions are fulfilled, the driving section increases the rotating speed of the paper discharge unit-side gear so that it is rotated at higher speed than before-acceleration speed over predetermined high-speed rotating period.

摘要： A feeding device according to the present invention holds a pile of sheets of paper in it. Feed force so acts selectively on a specified region of the upper side of the held top sheet as to feed the held sheets one after one in a feed direction. The feeding device includes a flat press plate and a support. The press plate is not smaller in the feed direction and the cross directions perpendicular to the feed direction than the maximum size of the sheets which can be held in the main body. The press plate is not larger in the feed and cross directions than the inner size of the main body. The press plate has a first opening formed over the specified region. The press plate is supported vertically movably above the held sheets by the support.
