摘要： In an image forming apparatus, a first photoconductor drum for use in at least in a monochrome printing mode is located upstream, in a direction of transport of a medium, of a plurality of second photoconductor drums for use in a color printing mode. A transfer bias for each of transfer members is regulated in such a manner that a transfer bias applied in the monochrome printing mode between a second photoconductor drum located adjacently downstream of the first photoconductor drum and the corresponding transfer member is larger than that applied in the color printing mode. A developing bias for each of the development rollers is regulated in such a manner that an absolute value of a developing bias voltage applied to a development roller corresponding to the first photoconductor drum in the monochrome printing mode is smaller than that applied in the color printing mode.

摘要： A image forming device includes a main casing, a photosensitive-member unit including a plurality of photosensitive members aligned in a first direction, and a belt disposed in confrontation with the photosensitive members. The photosensitive-member unit is movable in the first direction with respect to the main casing, and is pulled out of the main casing when pulled in a pull-out direction parallel to the first direction. The photosensitive-member unit is provided with a cleaning member that is disposed on an upstream side of a most-upstream one of the photosensitive members with respect to the pull-out direction. The cleaning member slidingly contacts the belt when the photosensitive-member unit is moved with respect to the main casing.

摘要： An image forming apparatus includes a transfer bias set up section and a developing bias set up section. The transfer bias set up section sets a transfer bias applied to each transfer member so that the transfer bias applied to a transfer member corresponding to a photosensitive member on the most downstream side is greater than a transfer bias applied to a transfer member other than this transfer member. The developing bias set up section sets a developing bias applied to each developing member to a first developing bias in a single-side printing mode, and sets up the developing bias applied to each developing member in formation of an image on a first surface and in formation of another image on a second surface to a second developing bias lower than the first developing bias when the image formed on the second surface is a color image.
