Image forming apparatus |
摘要 |
An image forming apparatus including: an intermediate transfer member configured to transfer the developer images on the plurality of photosensitive members; a secondary transfer member configured to transfer the developer images transferred onto the intermediate transfer member onto a recording sheet; a plurality of primary holding rollers provided to each of the plurality of photosensitive members, respectively; a collecting unit configured to collect developer remaining on the intermediate transfer member; and a control device configured to control biases applied to the secondary transfer member and the plurality of primary holding rollers, wherein, after printing control terminates, the control device is configured to perform cleaning control in which biases having opposite polarities to biases during the printing control are applied to the plurality of primary holding rollers and the secondary transfer member. |

1. An image forming apparatus comprising:
a plurality of photosensitive members configured to carry developer images; an intermediate transfer member configured to transfer the developer images on the plurality of photosensitive members; a secondary transfer member configured to transfer the developer images transferred onto the intermediate transfer member onto a recording sheet; a plurality of primary holding rollers provided to each of the plurality of photosensitive members, respectively, and configured to temporarily hold developer remaining on the photosensitive members; a collecting unit configured to collect developer remaining on the intermediate transfer member; and a control device configured to control biases applied to the secondary transfer member and the plurality of primary holding rollers, wherein, after printing control terminates, the control device is configured to perform cleaning control in which biases having opposite polarities to biases during the printing control are applied to the plurality of primary holding rollers and the secondary transfer member. |
