Abstract
A sheet feeding device comprises a sheet feeding member having an outer layer thereof, a sheet loaded on a sheet loading member being depressed on a peripheral surface of the outer layer, the sheet feeding member delivering the sheet depressed to the peripheral surface, through rotation of the peripheral surface. An inclination member having a depression portion and an inclined surface, the depression portion depressing the sheet on the peripheral surface, and a leading edge of the sheet being brought in contact with the inclined surface. The outer layer of the sheet feeding member is formed of a cross-linked rubber material which has a JIS-A hardness in a range between 25 degrees and 40 degrees, a tearing strength measured with a JIS B-type specimen, which is 10 N/mm or more, and a viscoelastic characteristic expressed by a loss tangent, which is 0.045 or less.
