    摘要： An image forming apparatus includes an image bearer, a transfer device contacting the image bearer to form a transfer portion, a transfer bias power source, and a controller. A ratio of a time period of application of the opposite-directional bias to a total time period of one cycle of the AC component of the superimposed bias is greater than 50%. A ratio of a value of the DC component of the superimposed bias output within a region ranging from a leading end of the recording medium to a predetermined length to a value of the DC component of the superimposed bias output outside the region is greater than a ratio of a value of the AC component of the superimposed bias output within the region to a value of the AC component of the superimposed bias output outside the region.

    摘要： A cleaning device includes a cleaner, a plurality of cleaning sub-units, a sub-unit holder, a detachable transmission assembly, and a plurality of joint couplers. The cleaner scrapes off adhered material from a surface of a cleaning target while contacting the surface of the cleaning target. The cleaning sub-units each includes a holder to hold the cleaner and a drive-receive rotator to receive a driving force. The sub-unit holder holds the cleaning sub-units. The detachable transmission assembly includes a driving-force receive rotator to receive a driving force from an external unit and a plurality of drive transmission rotators to transmit the driving force received by the driving-force receive rotator to the drive-receive rotators of the cleaning sub-units. The joint couplers mounted on the drive-receive rotators and the drive transmission rotators couple the drive-receive rotators with the drive transmission rotators in a rotation axial direction.

    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.

    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.
