A sheet material feeding apparatus capable of favorably guiding a sheet material to perform smooth feeding comprises a pair of rolls and first and second guide members and permits a sheet material to pass between the first guide member and the second guide member. One of the rolls has a plurality of circumferential grooves arranged between both ends of a sheet material feeding surface in an axial direction and spaced from one another in the axial direction, and the first guide member includes guide portions passing through the respective circumferential grooves and extending continuously to a downstream side from an upstream side between the pair of rolls in a sheet-material conveyance direction.
