摘要： An image forming apparatus include an image forming device, an image bearer, a transferrer, a cleaner, and an adhesion amount detector. The image forming device forms, on the image bearer, a toner image to be transferred to a recording medium and a toner image pattern to be input to the cleaner without being transferred to the recording medium. The cleaner cleans the image bearer. The adhesion amount detector detects a toner adhesion amount of the toner image. The toner image pattern is a belt-shaped pattern elongated in an orthogonal direction orthogonal to a traveling direction of the image bearer and having a greater amount of toner input to a portion of the cleaner corresponding to a position of the adhesion amount detector in the orthogonal direction than that input to a portion of the cleaner not corresponding to the position of the adhesion amount detector in the orthogonal 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.

摘要： An image forming apparatus includes a charging bias output device, a developing bias output device, a transfer bias output device, and a controller. The controller controls the transfer bias output device to supply a transfer bias from a time at which a first position of a photosensitive member arrives at a transfer position after the charging bias output device starts supplying a charging bias. An initial value of the transfer bias is controlled to be smaller than a normal set value for a predetermined time period (Tc) which is a time after the transfer bias starts to be supplied and within a time corresponding to a rise time (Ta) during which a surface potential of the photosensitive member reaches a predetermined potential after the charging bias starts to be output. The first position of the photosensitive member is a position at which the charging device start charging the photosensitive member.

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.
