摘要： A transfer device is provided including an intermediate transfer belt and transfer rollers associated with respective of photosensitive drums. Each of the transfer rollers and the intermediate transfer belt define therebetween a contact range of which center lies downstream of the center of a contact range (transfer nip region) defined between the associated photosensitive drum and the endless belt in the direction of movement of the endless belt. The transfer roller deforms the path of movement of the intermediate transfer belt by contacting the intermediate transfer belt, and the resulting deformation causes the intermediate transfer belt to contact the periphery of the photosensitive drum over a predetermined range.

摘要： For an electrostatic latent image formed on an image carrier (31b), besides an operation forming an “image forming electrostatic latent image” used to form the primary image, an operation is executed that forms an “electrostatic latent image for removing developer” for removing developer that resides on a developer supply member (53a) for a predetermined time period onto the image carrier (31b). Thus, developer is nearly eliminated from residing on this developer supply member (53a) in an overcharged state for a long period of time, and generation of a fogged image is avoided as much as possible.
摘要翻译：对于形成在图像载体（31b）上的静电潜像，除了形成用于形成主图像的“成像静电潜像”的操作之外，还执行形成“去除显影剂的静电潜像”以去除驻留在显影剂供应构件（53a）上的图像载体（31b）上的预定时间段的显影剂。因此，显影剂几乎从处于过充电状态的这种显影剂供给构件（53a）中长时间地排除，并且尽可能地避免产生雾化图像。
