A sheet feeding apparatus comprising, a feeding device for pinching a sheet and for selectively performing an operation for temporarily stopping a sheet supplied from an upstream side by abutting a leading end of the sheet against a nip of the feeding device and then feeding the sheet toward a downstream side and an operation for feeding a sheet supplied from the downstream side toward the upstream side; a guide mechanism shiftable between a first position near the nip to direct the sheet supplied from the upstream side to the nip of said feeding device, and a second position far away from the nip than the first position; and a biasing mechanism for biasing the guide mechanism to the first position when the feeding device feeds the sheet supplied from the upstream side toward the downstream side and for biasing the guide mechanism to the second position when the feeding device feeds the sheet supplied from the downstream side toward the upstream side.
