摘要： The image forming apparatus includes a process unit, a latent image writer, a power source, and a controller. The process unit is detachably attachable relative to the image forming apparatus and includes, as a single integrated unit, a latent image bearing member to bear a latent image on a surface thereof, a charging device to charge the surface of the latent image bearing member, and a development device to develop the latent image with toner. The controller causes the power source to output a charging bias at a predetermined target level supplied to the charging device. The process unit includes a first storage device to store correction information for calculating the predetermined target level of the charging bias in accordance with a combination of the latent image bearing member and the charging device. The controller corrects the predetermined target level based on the correction information in the first storage device.

摘要： 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.

摘要： 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.
