    摘要： An image forming apparatus includes an image bearer having an image bearing face to bear an image thereon; a transferer disposed opposing the image bearer, to transfer the image from the image bearing face onto a recording medium at a transfer section between the transferer and the image bearer; a first guide disposed upstream from the transfer section in a direction of delivery of the recording medium, to guide the recording medium to the transfer section; and a second guide upstream from the first guide and spaced away from the first guide, to guide the recording medium to the transfer section. Each of the first guide and the second guide extends in a lateral direction perpendicular to the direction of delivery. A leading end of the second guide in the direction of delivery is inclined from one end to the other end of the second guide in the lateral 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： A transfer device includes a nip forming member to contact a surface of an image bearing member to form a transfer nip therebetween, a pressing device, and a nip pressure changing device. The pressing device includes a plurality of elastic members, to produce a contact pressure between the nip forming member and the image bearing member according to a restoring force of at least one of the elastic members upon deformation of the elastic member. The nip pressure changing device changes an amount of elastic deformation of the elastic member between at least two stages to change a nip pressure of the transfer nip. While the contact pressure is produced by one of the elastic members, the nip pressure changing device changes the amount of elastic deformation of a different elastic member, different from the one that produces the contact pressure, to change the nip pressure of the transfer nip.
