摘要： This invention relates to an image forming apparatus in which a cleaning device is arranged above a photosensitive drum close thereto. The image forming apparatus has an image processing unit provided with the photosensitive drum. The photosensitive drum is constructed such that a gear portion formed in a flange member at one axial end of the photosensitive drum has a diameter not greater than an outer diameter of the photosensitive drum. The image processing unit is constructed such that a driving force from the image forming apparatus is transmitted to the photosensitive drum via the gear portion formed in the one flange member to rotate the photosensitive drum and is transmitted to at least one of image processor means via a gear portion formed in a flange member at the opposite axial end of the photosensitive drum. With this arrangement, a poor image formation due to a blocking phenomenon resulting from long stay of toner residues can be prevented and downsizing of the image forming apparatus is realized.

摘要： With the object of providing an imaging method that eliminates the occurrence of transfer ghosts, saves space and lowers costs, and by which image density irregularities do not arise, an imaging method utilized in a reverse-transfer system is disclosed. The reverse-transfer system is provided with, in order going round a photosensitive conductor 1, at least a main-charging stage 2, an exposure stage 3, a reverse-developing stage 4, a transfer stage 5, a separation stage 6 and a charge-stripping stage 7. The separation stage 6 applies a separation shift-bias voltage to the photosensitive conductor 1 surface. The separation shift-bias voltage is 1 kV or more, and is of the same polarity as that of the main-charging voltage that the main-charging stage 2 applies to the photosensitive conductor 1 surface. Making the separation shift-bias voltage 1 kV or more prevents transfer ghosts, and obtains images with a satisfactory absence of image density irregularities.
