摘要： A belt including a first roller is supported by a plurality of rollers, and is driven to rotate in a predetermined direction. An abutting member makes contact with at least one edge of the belt in its width direction. A pressing member applies a pressure on an extended surface of the belt in its thickness direction at a position near a contact portion of the belt with the abutting member and on an upstream side of the contact portion in its moving direction.

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.
