Abstract
A sheet feeding apparatus includes: a multiple-feed detecting section that detects recording sheets to be transported by plural rolls in a direction; a separating section that separates an uppermost sheet of the recording sheets from the other; a slippage detecting section that detects a slippage of the uppermost recording sheet with respect to a roll; and a transporting-speed reduction suppressing section that suppresses a transporting-speed of the uppermost recording sheet from reducing from a value, the separation section including: a transporting roll that transports recording sheets in a transporting direction; and a separation roll that is placed to be opposed to and to be press-contacted with the transporting roll through a recording sheet, the transporting-speed reduction suppressing section changing a separation torque of the separation roll according based on a result of detection by the multiple-feed detecting section and a result of detection by the slippage detecting section.
