摘要： An image forming apparatus includes a transfer belt unit which has an intermediate transfer belt for supporting toner images and primary transfer rollers for pressing the intermediate transfer belt against corresponding photoreceptor drums and moves the intermediate transfer belt along the surface of each photoreceptor drum to transfer the toner images to the intermediate transfer belt. The intermediate transfer belt is formed so as to be 30 μm to 50 μm in average thickness, each primary transfer roller is arranged at a position, along the moving direction of the intermediate transfer belt, which is deviated downstream with respect to the moving direction from the position where the intermediate transfer belt is in contact with the photoreceptor and which is projected toward the photoreceptor drum side so as to press the intermediate transfer belt against photoreceptor with a nip pressure ranging from 10 gf/cm2 to 40 gf/cm2.

摘要： A belt conveyor member includes an endless belt and a cleaning blade. The cleaning blade is configured to remove residual toner remaining on a surface of the endless belt which is processed into a smooth surface. The endless belt has a first region and a second region. The first region is a region in contact with the cleaning blade which is located outside a region for a recording sheet of a maximum usable width to pass therethrough. The second region is located outside the first region. A contact surface between the cleaning blade and the first region is in a rough condition free from intimate contact.
摘要翻译：带式输送机构件包括环形带和清洁刮板。清洁刮板被构造成去除残留在被加工成光滑表面的环形带的表面上的残留调色剂。环形带具有第一区域和第二区域。第一区域是与清洁刮板接触的区域，其位于用于通过其中的最大可用宽度的记录片材的区域的外侧。第二区域位于第一区域之外。清洁刮板与第一区域之间的接触表面处于粗糙状态，没有紧密接触。

摘要： An image forming apparatus includes a PTC and a toner concentration sensor that are disposed adjacent to and downstream of a fourth image forming unit. The PTC and the toner concentration sensor are opposed to an intermediate transfer belt. A counter roller is opposed to the PTC across the intermediate transfer belt. The counter roller moves to, during the toner concentration detection, a position opposed to the toner concentration sensor across the intermediate transfer belt. Compared to the PTC and the toner concentration sensor each having a counter roller, less rollers may be provided, thereby reducing degradation of the intermediate transfer belt due to wear.
摘要翻译：图像形成装置包括邻近于第四图像形成单元的下游设置的PTC和调色剂浓度传感器。 PTC和调色剂浓度传感器与中间转印带相对。反向辊与中间转印带上的PTC相对。在调色剂浓度检测期间，反向辊移动到与中间转印带上的调色剂浓度传感器相对的位置。与具有反向辊的PTC和调色剂浓度传感器相比，可以提供较少的辊，从而减少中间转印带由于磨损而的劣化。
