摘要： An image forming apparatus includes a photosensitive belt carried by a driver device, for forming a toner image thereon; an internal transcription belt for transcribing the toner image; and a transcription portion for transcribing the toner image, which is transcribed on the internal transcription belt, onto a recording medium. A transcription side roller is suspended with the internal transcription belt thereon, and disposed on a side of a photosensitive belt side roller. Detectors detect a first cycle of the internal transcription belt, and a second cycle, which starts measurement delaying by ½ cycle of the photosensitive belt side roller from the first cycle measurement start. A controller conducts speed compensation of the photosensitive belt by referring to the first cycle and the second cycle, wherein the internal transcription belt is in contact with the photosensitive belt, so that it is carried following thereafter.

The intermediate transfer device is an intermediate transfer belt contacted by the photoreceptor belt to be driven thereby. A photoreceptor-side roller enables contact of the intermediate transfer belt and the photoreceptor belt, and the intermediate transfer belt is trained around the photoreceptor-side roller and a transfer-side roller for pushing the sheet against the transfer roller. A diameter d2 of the transfer-side roller is smaller than a diameter d1 of the photoreceptor-side roller.

摘要： Two pairs of legs are fitted under two side plates of an electrophotography apparatus, respectively. The two legs in one pair fitted under one of the side plates are disposed on either side of and are spaced from a point which is a cross point of a line joining these two legs, and a line perpendicular to this line, which perpendicular line passes through a projected point obtained by projecting the center of gravity of the electrophotography apparatus onto a horizontal plane on which the apparatus is set up. The two legs in the pair fitted under the other one of the side plates are disposed on either side of and are spaced from a point which is a cross point of a line passing these two legs and a line perpendicular to this line, which perpendicular line passes through the projected point of the center of gravity. The ratio of a shorter distance to a longer distance, of two distances: one between the two legs in a pair and the other between the two legs in the other pair is set to a value of 1/5 to 1/3. With such a arrangement, a defect in an image caused by a distortion in said side plates, due to a position change in the center of gravity of the electrophotography apparatus can be prevented.

摘要： A fixing unit where an operating force for releasing a nip can be reduced with a small-sized configuration. The fixing unit has a heating roller including a heating element, a pressure belt, pressure arms, pressure springs, and nip load releasing units. The pressure belt is supported in an intermediate position between the pressure arms 3. One end portions of the pressure arms are brought into contact with the pressure springs respectively. The other end portions of the pressure arms are brought into contact with the nip load releasing units respectively. When a load applied to the pressure belt is released by the nip load releasing units, the other end portions of the pressure arms move away from the heating roller.
