摘要： The present invention relates to an image forming apparatus that forms an image by consecutively superposing toner images that have been formed on a plurality of photosensitive drums, on an intermediate transfer member or a transfer medium. The image forming apparatus is made compact and operates at a low cost. Since a current supply member supplies a current in a rotational direction of an intermediate transfer belt, multiple first transfer portions do not need corresponding voltage sources. Even in the case where a charging member supplies a current, the potential of the intermediate transfer belt is maintained at a predetermined potential by a constant-voltage element connected to support rollers.
摘要翻译：本发明涉及一种图像形成装置，其通过连续叠加已经形成在多个感光鼓上的调色剂图像，在中间转印部件或转印介质上形成图像。成像装置紧凑并且成本低。由于电流供给部件在中间转印带的旋转方向上供给电流，所以多个第一转印部不需要对应的电压源。即使在充电部件供给电流的情况下，通过连接到支撑辊的恒压元件将中间转印带的电位维持在预定电位。
