Sheet conveying device and image forming apparatus

A sheet conveying device comprising:

• a first roller and a second roller that constitute a pair of conveying rollers rotatably disposed opposite each to convey a sheet;
• and
• at least one pressing portion that presses the first roller toward the second roller at a position inward of opposite end parts of the pair of conveying rollers along an axial direction,
• wherein
• the pressing portion includes:
• a pressing member that contacts the first roller from a side thereof opposite from the second roller;
• a pressing urging member that urges the pressing member toward the second roller, and
• the first roller has a step portion that is formed in an outer circumferential part of the first roller all over a circumference thereof, the step portion having an outer diameter smaller than an outer diameter of a contact region with the second roller, the step portion being contacted by the pressing member,
• the first roller is rotatably supported on a body frame of an apparatus body, and
• the sheet conveying device further comprises:
• a bush member that is supported on the body frame so as to be movable along a radial direction of the first roller, the bush member rotatably supporting the second roller;
• and
• a counter-urging member that urges the bush member in such a direction that the second roller comes closer to the first roller.
