摘要： A belt member of the present invention includes ribs that prevent the belt member from being shifted to either side. A plurality of cuts are formed in each rib at preselected intervals in the circumferential direction of the belt member, and each extends from the top toward the bottom of the rib. The cuts may be replaced with projections and recesses alternating with each other in the cicumferential direction of the belt member or bores formed at preselected intervals in the above direction. Such ribs allow, without being subject to a heavy load, the belt member to be wrapped around a support roller with a large curvature or bent in the inverse direction. This reduces deterioration and slippage ascribable to the position of the belt member desirable for the size reduction of an apparatus on which the belt member is mounted.
摘要翻译：本发明的带构件包括防止带构件向任一侧移动的肋。多个切口沿带部件的圆周方向以预定间隔形成在每个肋中，并且每个切口均从肋的顶部朝向底部延伸。这些切口可以用沿着带构件的圆周方向相互交替的凸起和凹槽代替，或者在上述方向上以预定的间隔形成孔。这样的肋允许在不承受重负荷的情况下将带构件缠绕在具有大曲率的支撑辊上或沿相反方向弯曲。这减少了由于安装带构件的设备的尺寸减小而期望的带构件的位置所引起的劣化和滑动。

摘要： Driving voltages of an LED of each color are stored in applied voltage storage register 11, 12 or 13, and the LED of each color is driven with independent driving voltage, whereby current consumption is reduced. Further, data in applied voltage storage registers 11, 12 and 13 is made rewritable via storage value setting bus 14, and when there are fluctuations in minimum emission voltage in actually mounted LEDs due to individual differences, voltages to store in the applied voltage storage registers 11, 12 and 13 can be changed as appropriate corresponding to the fluctuations.

摘要： The present invention is aimed at carrying out high-precision and stable image formation using a gray-level image forming technique. In carrying out image formation by a gray-level electrophotographic process, the relationship between the layer thickness Tp of the photosensitive layer on the photosensitive member and the exposure diameter Db of a light beam emitted onto the photosensitive member is defined as 2Tp 2 with respect to the peak value of the exposure distribution obtained by integrating the energy distribution of the light beam with the exposure time. In this manner, excellent gray-level image presentation can be obtained, and high-precision and stable image formation can be carried out by using a region of damping characteristics on the photosensitive member.

摘要： Power is supplied from a capacitor (C) of an auxiliary power source (4) to a secondary heating element (2b) of a heating unit (2), thereby preventing temperature drop of a fixing roller (40) at the time of continuous paper delivery. An allowable range for starting discharge from the capacitor (C) is set to, for example, 30 to 40 volts. A discharge time in which the voltage of the capacitor (C) reduces to a termination value, such as 20 volts, is longer than a time necessary for a reading unit (11) to read a maximum number (for example, 100 sheets) of documents that can be read at one time.
