发明名称 COLOUR PICTURE IMAGE FORMATION DEVICES
摘要 A colour picture image formation device includes a plurality of image formation sections (P min ), each containing a photosensitive body drum (17), a charge unit (18), an exposure unit (19) and a developing unit (20). The image formation sections produce toner picture images of different respective colours. The device also includes an intermediate transfer body (15) for receiving, and superimposing on one another, the toner picture images from the photosensitive body drums (17) of the image formation sections and for transferring the combined toner picture image to recording paper (100). The intermediate transfer body (15) is constructed and connected to permit the potential at its surface to differ at different locations thereon, thereby permitting different primary transfer voltages to be generated, between the transfer body (15) and the photosensitive body drum (17), for the different image formation sections (P min ). The transfer section of the intermediate transfer body (15), from which the toner images are transferred to the recording paper (100), can be grounded to permit the secondary transfer voltage to be reduced. <IMAGE>
