Image forming apparatus including re-conveying unit

An image forming apparatus comprising:

• an image forming unit configured to form an image on a sheet;
• and
• a re-conveying unit configured to re-convey the sheet on which an image is formed toward the image forming unit in a re-conveying direction, the re-conveying unit comprising:
• a first roller configured to rotate about a first axis perpendicular to the re-conveying direction, the first roller having a first circumferential surface made from rubber and configured to contact with the sheet;
• a second roller facing the first roller and having a second circumferential surface which is configured to contact with the sheet and is made from material more rigid than the rubber, the second roller being configured to rotate about a second axis inclined with respect to the first axis, the second roller having a first end portion and a second end portion in a direction of the second axis, the second end portion positioned upstream of the first end portion in the re-conveying direction;
• a pressing member configured to exert resilient force to urge the second roller toward the first roller;
• and
• a regulating member configured to restrict at least one of the first end portion and the second end portion from moving toward the first roller, the regulating member positioned adjacent to the second end portion.
