摘要： An image forming apparatus includes a transfer device to transfer a toner image onto a recording medium with a transfer bias applied thereto, a recording medium conveyor to deliver the recording medium to a transfer region while controlling an alignment of the recording medium having entered the transfer region in alignment control, and a transfer bias controller to obtain a toner adhesion amount information on a post-alignment-control toner image that passes through the transfer region after the recording medium is free from the alignment control, and to reduce, when the toner adhesion amount per unit area is less than a predetermined amount, the transfer bias after the alignment control is released to a level less than that of a transfer bias that is applied when the toner image having a same toner adhesion amount passes through the transfer region before the recording medium is free from the alignment control.

摘要： An image forming apparatus includes an image bearer; a toner image forming unit, a transfer unit, a detector, and a controller. The toner image forming unit forms a plurality of types of density detection patterns on the surface of the image bearer in mutually-different positions in a surface-movement direction of the image bearer. The density detection patterns have mutually-different lengths in a direction orthogonal to the surface-movement direction of the image bearer. The transfer unit transfers the density detection patterns onto the surface of the transfer member. The detector detects image densities of the density detection patterns transferred on the surface of the transfer member. The controller calculates an image density difference between the density detection patterns on a basis of a detection result obtained by the detector, and corrects a transfer bias for transferring a toner image on a basis of a value of the image density difference.
