Abstract: An image forming apparatus includes an image carrier, a transferor, a fixing unit, and a guide. The image carrier carries a toner image. The transferor opposes the image carrier to form a transfer nip and transfers the toner image on the image carrier onto a recording medium at the transfer nip. The fixing unit fixes the toner image on the recording medium. The guide guides the recording medium bearing the toner image from the transferor toward the fixing unit and includes a surface portion directly contacting the recording medium. The surface portion includes a material for charging the recording medium to have a polarity opposite to the polarity of a toner forming the toner image.

Abstract: A transfer device includes an image bearing member, a transfer member, a test image detector, and a shield member. The image bearing member bears a toner image on a surface thereof within an image forming area. The transfer member disposed opposite the image bearing member forms a transfer nip between the transfer member and the image bearing member through which the recording medium is conveyed and transfers the toner image from the image bearing member onto the recording medium in the transfer nip. The test image detector disposed downstream from the transfer nip in the direction of conveyance of the recording medium detects a density of a test image for adjustment of toner density formed outside the image forming area. The shield member disposed between the test image and the transfer member shields the test image from an electrical field generated between the image bearing member and the transfer member.

Abstract: After an image forming operation is finished, a motor that drives a belt is stopped after a predetermined time period passes since a sensor detects the only one mark provided on the belt. The predetermined time period is different for first, second and third job. This is repeated for the jobs thereafter. One job is a series of processing from the start of the motor to the stop of the motor. Thus, the belt stops at three different position for each consecutive three jobs.

Abstract: An image forming apparatus includes a rotatable image bearer, an exposure device, a development unit, an adjuster, and a magnetic member. The exposure device forms a latent image on a surface of the image bearer. The developing unit renders the latent image visible with developer including toner and carrier. The adjuster contacts each of the image bearer and the exposure device to regulate a distance between the image bearer and the exposure device. The magnetic member is arranged side by side with the adjuster in a direction of rotation of the image bearer.

Abstract: An electric charging-diselectrifying device includes an electric charging member that contacts an image bearer to form an electric charging nip between the electric charging member and the image bear. The electric charging member electrically charges multiple electric charge regions in the image bearer located both upstream and downstream of the electric charging nip in a direction of rotation of the image bearer. An electric charge removing device is provided to remove electric charge borne on the image bearer by irradiating the multiple electric charging regions of the image bearer with light. The electric charging member is made of a material that allows the light emitted from the electric charge removing device to penetrate the electric charging member.

Abstract: A charging device includes a charger and a power supply circuit. The charger is disposed opposing a latent image bearer. The power supply circuit applies to the charger an alternating voltage obtained by superimposing a pulsating voltage on a direct-current voltage. The alternating voltage generates normal discharge from the charger to a surface of the latent image bearer and reverse discharge from the surface of the latent image bearer to the charger. A pulse ON time of a voltage component toward a reverse discharge side relative to a desired surface potential Vde of the latent image bearer is shorter than a pulse ON time of a voltage component toward a normal discharge side relative to the desired surface potential Vde of the latent image bearer.
