A feeding apparatus comprises a blower unit that is able to perform a first air blowing operation on sheets which are stacked on a stacking unit, and a second air blowing operation in which the volume of air blowing is smaller than volume of air blowing in the first air blowing operation; a feeding unit, brought into contact with the sheets stacked on the stacking unit and located on a feeding position to which feeding is performed while pressing the sheets from above, for feeding the sheets on which the first air blowing operation has been performed; and a control unit for controlling the blower unit to perform the first air blowing operation until a start of feeding by the feeding unit so as to separate the sheets stacked on the stacking unit.

An image forming apparatus has a sheet feed portion, a conveying portion, a control portion, a first sensor having the detection position at a first position in the sheet conveying passage, and a second sensor having the detection position at a second position downstream of the first position in the sheet conveying direction. The control portion performs first sensing to sense whether the sheet's rear end has passed the first position within a first time of the start of the feeding and second sensing to sense whether the sheet's rear end has passed the second position within a second time of the start of the feeding, Even if the control portion is unable to sense passage of the sheet's rear end in the first sensing, when it senses passage of the sheet's rear end in the second sensing, it makes the conveying portion continue feeding the sheet.

Examples described herein include a print media edge repair system that includes a first repair element disposed adjacent to a media handling path to repair a leading edge of a sheet of print media as the sheet of print media moves into a position relative to a printing system associated with the print media edge repair system. The print media repair system may also include a second repair element disposed opposite the first repair element across the media handling path to repair a trailing edge of the sheet of print media as the sheet of print media moves into the position relative to a printing system.

A paper supply apparatus includes: a primary paper supply roller that feeds out and conveys a print medium from a paper tray on which the print medium is placed; resist rollers that a leading end of the print medium abuts to form a flexure in the print medium by temporarily ceasing conveyance, and rotate at a predetermined timing after this flexure is formed, to convey the print medium toward a conveyance mechanism; and a control unit that executes assist control that drives the primary paper supply roller during the time that the print medium is being conveyed by the resist rollers to assist conveyance of the print medium by the resist rollers. The control unit executes the assist control such that the flexure in the print medium remains at a point in time at which the leading end of the print medium reaches the conveyance mechanism.
