摘要： An endless belt is supported by a plurality of rollers. A transfer roller comes in contact with an outer surface of the belt to form a transfer nip. An auxiliary member makes contact with a recording medium on an upstream side of the transfer nip in a movement direction of the belt, to cause the recording medium to be in close contact with the outer surface of the belt. A bias applying unit applies to the auxiliary member a bias for electrostatically transferring a toner adhered to the auxiliary member to the outer surface of the belt.

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.

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： A heating device includes an endless rotator that rotates in a rotation direction and a heater that contacts an inner circumferential surface of the endless rotator and extends in an axial direction of the endless rotator. An elastic body contacts the inner circumferential surface of the endless rotator and is disposed downstream from the heater in the rotation direction of the endless rotator. A holder holds the heater and the elastic body. A pressure rotator is disposed opposite the heater and the elastic body via the endless rotator to form a nip between the endless rotator and the pressure rotator. A motion restrictor is mounted on the holder. The motion restrictor restricts motion of the heater downstream in the rotation direction of the endless rotator.
