    摘要： An apparatus includes an image bearing member for carrying an image; an intermediary transfer member for receiving the image; a primary transfer member for transfer of the image onto the intermediary transfer member in a primary transfer station; a secondary transfer member for transfer of the image onto a transfer material in a secondary transfer station; a first charging member for charging toner remaining in a region upstream of the primary transfer station and downstream of the secondary transfer station; and a second charging member for charging the toner remaining in a region upstream of the primary transfer station and downstream of the first charging member. The first charging member rubs a surface of, and the second charging member moves in contact with, the intermediary transfer member, to transfer the toner remaining on the intermediary transfer member to the image bearing member simultaneously with the primary transfer.

    摘要： An image forming apparatus includes an image bearing member for bearing a toner image; an endless rotatable intermediary transfer belt onto which the toner image is to be transferred from the image bearing member; a transfer device disposed at a position in which the transfer device opposes the image bearing member through the intermediary transfer belt, the transfer device including a sheet member surface-contacted to an inner surface of the intermediary transfer belt and including an urging member for urging the sheet member toward the intermediary transfer belt; and a primary transfer voltage source for applying a voltage to the sheet member. With respect a rotational direction of the intermediary transfer belt, an upstream end portion of a contact area formed between the intermediary transfer belt and the sheet member and an upstream end fportion of a contact area formed between the sheet member and the urging member are within a range of a contact area formed between the intermediary transfer belt and the image bearing member. The upstream end portion of the contact area formed between the intermediary transfer belt and the sheet member is located upstream of the upstream end portion of the contact area formed between the sheet member and the urging member.

    摘要翻译： 图像形成装置包括用于承载调色剂图像的图像承载部件; 一个环形的可旋转的中间转印带，调色剂图像将从该图像承载部件转印到该转印中心转印带上; 转印装置，其设置在转印装置通过中间转印带与图像承载部件相对的位置处，该转印装置包括与中间转印带的内表面表面接触的片状部件， 片材朝向中间转印带; 以及用于向片材施加电压的一次转印电压源。 关于中间转印带的旋转方向，形成在中间转印带和片状部件之间的接触区域的上游端部分和形成在片材部件和推压部件之间的接触区域的上游端部分分别位于 在中间转印带和图像承载部件之间形成的接触区域的范围。 形成在中间转印带和片状部件之间的接触区域的上游端部位于形成在片状部件和推压部件之间的接触区域的上游端部的上游。
