摘要： An image forming apparatus includes a developing device that uses a developer carrier to advance to an image carrier a developer including a toner and a carrier and supplies the toner to the image carrier by applying a developing bias between the developer carrier and the image carrier. In the image forming apparatus, the following operation is performed before the developer in the developing device is taken out. The toner is supplied to the image carrier by applying the developing bias between the developer carrier and the image carrier, the developing bias increased in a direction to supply the toner to the image carrier. The toner supplied onto the image carrier is not transferred to a transfer receiving material but is advanced into a toner recovery device for recovery. The recovered toner is prevented from being returned to the developing device.

摘要： A sheet feeding device having: a first conveyance roller pair that feeds a sheet; a second conveyance roller pair that feeds the sheet, the second conveyance roller pair being provided downstream from the first conveyance roller pair in a feed direction in which the sheet is fed; and a third conveyance roller pair that feeds the sheet, the third conveyance roller pair being provided downstream from the second conveyance roller pair in the feed direction, in which, when an edge of the sheet that is located on the downstream side of the feed direction is skewed with respect to a direction perpendicular to the feed direction, the second conveyance roller pair slides in the perpendicular direction with the sheet slacking between the first conveyance roller pair and the second conveyance roller pair.
