Color image forming apparatus with intermediate transfer member |
摘要 |
The present invention relates to the cleaning of an intermediate transfer member of an image forming apparatus for transferring a toner image formed on a photosensitive member onto the intermediate transfer member and then transferring the toner image onto a transfer material. An effective cleaning width of a cleaning means for removing residual toner remaining on the photosensitive member in a width-wise direction of the photosensitive drum is selected to become greater than a longitudinal dimension of the intermediate transfer member, the longitudinal dimension of the intermediate transfer member is selected to become greater than a width of a transfer electrode for transferring the toner image on the intermediate transfer member, and the longitudinal dimension of the intermediate transfer member is selected to become greater than a charge width of an electrode for charging the residual toner on the intermediate transfer member to return the toner to the photosensitive member.
