Abstract
A roller comprises a rotary shaft, an outer peripheral wall member for defining an outer peripheral surface to be contacted with a sheet, and a support member for supporting the outer peripheral wall member so that the outer peripheral wall member surrounds the rotary shaft. The support member defines a space between the rotary shaft and the outer peripheral wall member and supports the outer peripheral wall member with maintaining a condition that the outer peripheral wall member is deformed to swell radially outwardly.
