Abstract: An image forming apparatus having an image bearing member for carrying an image, a transfer member for urging a recording sheet against the image bearing member and transferring an image onto the recording sheet, a driving means for rotationally driving the image bearing member, and a driving force transmission means for transmitting a driving force from the driving means to the transfer member through the image bearing member. The transfer member is then rotated so that the peripheral speed of a portion of the transfer member which urges the sheet against the image bearing member is higher than the peripheral speed of the image bearing member. The image forming apparatus satisfies the following inequality: R.sub.D W.sub.D <R.sup.1 W.sub.T, where R.sub.D is the radius of the image bearing member, R.sup.1 is the minimum radius of the transfer member, W.sub.D is the angular velocity of the image bearing member and W.sub.T is the angular velocity of the transfer member.

Abstract: A sheet feeding apparatus includes a feeding roller for feeding a sheet material from a stack of sheet materials, a separation device for cooperating with the feeding roller to allow only one sheet material to be fed, a transportation roller for cooperating with the feeding roller to transport the sheet material separated by the separating device.
