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 includes a latent image bearing member, a charging unit, a charging power source, a latent image writing unit, a development unit, a transfer unit, a toner detector, and a controller. The controller causes a background fog pattern to be formed on a surface of the latent image bearing member. In addition to the background fog pattern, the controller causes a latent image to be developed to form a toner image used for position identification on the surface of the latent image bearing member. The controller identifies a time when the toner image used for position identification has entered a detection range of the toner detector based on a change in outputs of the toner detector to determine a time when each of sections of the background fog pattern enters the detection range based on the identified time.

摘要： An image forming apparatus include a latent image bearer, charger, latent image forming unit, developing unit, receiver unit, transfer unit, information acquisition unit, and correction unit. The charger charges the latent image bearer with a predetermined charging potential. The latent image forming unit forms an electrostatic latent image on the latent image bearer. The developing unit develops the electrostatic latent image to form a toner image. The receiver unit receives the toner image from the talent image bearer. The transfer unit applies a predetermined transfer bias to transfer the toner image to the receiver unit. The information acquisition unit acquires residual image generation determination information. When predetermined residual image generation condition is satisfied, a correction unit corrects image forming condition such that surface potential unevenness of the latent image bearer subsequent to transfer is smaller than that generated where predetermined residual image generation condition is not satisfied.

摘要： An image forming apparatus includes an image bearer, a transfer member, a cleaning member, and a control unit. The transfer member contacts the image bearer to form a transfer nip and transfer a toner image on the image bearer to a recording medium at the transfer nip. The cleaning member cleans a surface of the image bearer. The control unit executes a cleaning operation of moving an extraneous matter adhering to the transfer member to the image bearer to clean the transfer member. The control unit executes the cleaning operation after a toner image pattern that is not transferred to the recording medium passes through the transfer nip and before the recording medium enters the transfer nip.
