摘要： An image forming apparatus includes an image bearing member to bear a latent image on a surface thereof, a developing device to develop the latent image with toner, an intermediate transfer member, a secondary transfer member, a cleaning device, and a main body. The cleaning device cleans the secondary transfer member for a predetermined time period T1 during a startup operation after printing is completed normally before subsequent printing. The main body houses the image bearing member, the developing device, the intermediate transfer member, the secondary transfer member, and the cleaning device. At least one of the image bearing member and the developing device constitutes a process cartridge detachably attachable relative to the main body, and in a case in which the process cartridge is installed in the main body, the cleaning device cleans the secondary transfer member for a time period T2 extended from the predetermined time period T1.

摘要： An image forming apparatus includes a photosensitive member, a charging device, an exposure device, a development device, a transfer device, a first driving device, a voltage application device, and a controller. The first driving device rotatably drives one of the photosensitive member and a combination of the photosensitive member and an intermediate transfer member. The voltage application device supplies a respective predetermined voltage to the charging device, the development device, and the transfer device. The controller controls the first driving device and the voltage application device. When the photosensitive member is stopped, both illumination from the exposure device and the transfer electrical field electrically discharge the surface of the photosensitive member.

摘要： An image forming apparatus including a latent image bearing member, a charger, a latent image forming device, a developing device, and a transfer device is provided. The transfer device is adapted to transfer a toner image formed on the latent image bearing member onto an intermediate transfer member or a recording medium by action of a transfer elected field in a transfer position where the latent image bearing member faces the transfer device. When a non-charged portion of the latent image bearing member that has not been charged to a predetermined potential by the charger passes through the transfer position, a strength of the transfer electric field is lowered than that in transferring the toner image.
