摘要： A separation unit is provided on a downstream side of a contact area between a belt-like rotating body and a pressure rotating body. The separation unit includes a pressure member, a guide portion and a pressure portion. The pressure member extends along a width direction of the belt-like rotating body, and presses the belt-like rotating body to deform the belt-like rotating body into a bent shape changing a course away from a surface of the pressure rotating body. The guide portion is on the pressure rotating body side of the pressure member to guide the belt-like rotating body so that an angle portion of the bent shape bites into the pressure rotating body. The pressure portion is on the surface in the pressure rotating body side, and the surface separates sequentially from the pressure rotating body in the extending direction from a center portion to an end portion.

摘要： A transfer device includes a transfer device, a facing member, and a prepressing member. The transfer member transfers a toner image, which is carried on an intermediate transfer member, to a recording medium. The facing member is disposed so as to be in pressed contact with the transfer member with the intermediate transfer member therebetween. The prepressing member is disposed so as to be in pressed contact with the transfer member with the intermediate transfer member therebetween at a position that is upstream of a contact section in which the facing member is in pressed contact with the transfer member and that is immediately behind a position at which the toner image starts to come into contact with the recording medium. A pressure applied by the prepressing member is lower than a pressure with which the facing member is in pressed contact with the transfer member.
