1. An image forming apparatus comprising:
- an image bearing member configured to bear a toner image;
a movable intermediate transfer member configured to bear the toner image transferred thereto from the image bearing member; and
a transfer unit configured to transfer the toner image from the intermediate transfer member to a recording material,wherein the transfer unit comprises;
a first transfer inner roller for supporting the intermediate transfer member from an inner peripheral surface and transferring the toner image to the recording material from the intermediate transfer member;
a second transfer inner roller arranged on the downstream side of the first transfer inner roller in the moving direction of the intermediate transfer member and supporting the intermediate transfer member from the inner peripheral surface and transferring the toner image to the recording material from the intermediate transfer member;
a first transfer outer roller arranged so as to be deviated downstream from the first transfer inner roller in the moving direction of the intermediate transfer member and forming a first transfer portion configured to pinch the intermediate transfer member between itself and the first transfer inner roller and to transfer the toner image to the recording material from the intermediate transfer member; and
a second transfer outer roller forming a second transfer portion configured to pinch the intermediate transfer member between itself and the second transfer inner roller and to transfer the toner image to the recording material from the intermediate transfer member,wherein the first transfer inner roller and the first transfer outer roller are arranged such that the first transfer inner roller has a portion pushing the intermediate transfer member toward the side where the first transfer outer roller is arranged beyond an extension of the intermediate transfer belt between the first transfer portion and the second transfer portion.
