Abstract: An image forming apparatus in which a visible image is transferred to a transfer material includes a pre-transfer exposing unit that makes only a portion of a latent image carrier that corresponds to a leading edge of the transfer material expose, and a transfer-bias applying unit that applies a bias for transferring the visible image. The transfer-bias applying unit starts applying the bias to the transfer material, at least step-by-step, when a predetermined time is passed from a point of time at which the leading edge of the transfer material comes into a contact with the latent image carrier by controlling the pre-transfer exposing unit and a bias applying timing of the transfer-bias applying unit.

Abstract: A transfer unit includes a belt member, a bending roller, a transfer section, and a bias application unit. The belt member is extended between rollers and has a movable surface on which a toner image is transferred from an image carrier. The bending roller externally contacts the surface of the belt member to bend the belt member and rotates in conjunction with the belt member. The transfer section includes one of the rollers and a surface moving member. The surface moving member rotates at least one full turn while cleaning is performed on the surface moving member and the bending roller. A surface moving speed of the bending roller is equal to or greater than a surface moving speed of the surface moving member. A circumferential length L1 of the surface moving member and a circumferential length L2 of the bending roller satisfy L1≧L2.

Abstract: An image transferring and recording medium conveying device, for an image forming apparatus, which includes a nip between a belt and an image carrier for image transfer to a recording medium. A bias applying device applies a bias for image transfer to the nip. An image transfer bias Tb is applied during a leading edge interval, in which the leading edge portion of the recording medium between the leading edge and a preselected position in the direction of medium conveyance moves away from the nip. An image transfer bias Ta is applied to the nip during a remaining interval, in which the remaining portion of the recording medium moves away from the nip. A controller switches the image transfer bias Tb within a range lower than the image transfer bias Ta and greater than an image transfer bias Tc.
