Patent ID: 7163202

Claim:
A sheet feeding device comprising: 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 of the sheet feeding member, the sheet feeding member delivering the sheet depressed to the peripheral surface, through rotation of the peripheral surface; and an inclination member having a depression portion and an inclined surface located at an upstream side of the depression portion in a sheet delivery direction, the depression portion depressing the sheet on the peripheral surface, a leading edge of the sheet being brought in contact with the inclined surface, the inclination member being supported movably in a direction to approach to or separate from the peripheral surface, an inclusion angle between the inclined surface of the inclination member and an outgoing direction of the sheet being set as an acute angle so that the leading edge of the sheet in contact with the inclined surface is guided through the inclined surface for delivery to the depression portion, and an inclusion angle between the depression portion and the inclined surface being set as being less than 180 degrees, wherein 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.
