摘要： A cleaner includes a cleaning member electrostatically removing toner on an object; a first electricity supplier supplying a first voltage (or current) with polarity opposite to that of toner to the cleaning member; a toner collecting member collecting toner from the cleaning member; and a second electricity supplier supplying a second voltage with the polarity greater than the first voltage to the toner collecting member. The first and second electricity suppliers set plural setting values of the first and second voltages smaller than the targeted values of the first and second voltages, and first and second control members of the first and second electricity suppliers output first and second control signals while changing in step-by-step manner so that first and second output members of the first and second electricity suppliers apply the first and second voltage in step-by-step manner before the first and second voltages reach the targeted voltages.

摘要： An image forming apparatus includes an image bearer on which a toner image is formed, an intermediate transfer belt onto which the toner image transferred from the image bearer, a secondary transfer member, a guide assembly, and a biasing device. The secondary transfer member meets the intermediate transfer belt to form a secondary transfer nip in which the toner image is transferred from the intermediate transfer belt onto a recording sheet. The guide assembly disposed upstream from the secondary transfer member in a transport direction of the recording sheet guides the recording sheet at a position lower than the secondary transfer nip such that a leading end of the recording sheet contacts the secondary transfer member before entering the secondary transfer nip. The biasing device biases the secondary transfer member to move the secondary transfer member in one of a direction of bias and a vertical direction.

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.
