摘要： An image forming apparatus includes a control device executing: a holding process of holding developer attached on an image carrier at a holding member; a moving process of moving the developer from the holding member to the image carrier; and a collection process of collecting the developer attached on the image carrier into a collection member. The control device executes the moving process and the collection process after completing printing. The control device sets a first flag when predetermined time period elapses from start of the moving process and unsets the first flag at start of the printing. When the first flag is not set at a startup time, the control device executes the moving process and the collection process before the printing. When the first flag is set, the control device omits the moving process before the printing.

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.
