    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: As one embodiment, a paper feeding device is provided with a pickup roller for pulling out an uppermost positioned sheet of loaded sheets, and a paper feeding roller for transporting the sheet pulled out by the pickup roller. Spanning between the pickup roller and the paper feeding roller, a roller belt is provided that is capable of moving relatively in a circumferential direction with respect to an outer circumferential surface of the paper feeding roller. The roller belt obtains rotational drive from the pickup roller.
