摘要： A fixing device includes a nip formation pad disposed opposite an inner circumferential surface of an endless belt and a pressing rotary body pressed against the nip formation pad via the endless belt to form a fixing nip between the endless belt and the pressing rotary body, through which a recording medium is conveyed. The pressing rotary body has a diameter increasing from a center to each lateral end in an axial direction thereof. The nip formation pad includes a projection disposed downstream from a rotation axis of the pressing rotary body in a recording medium conveyance direction. The projection projects toward the pressing rotary body in an amount increasing from each lateral end to a center in a longitudinal direction of the nip formation pad parallel to the axial direction of the pressing rotary body.

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 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.
