Abstract:
The feeding apparatus includes a pick-up roller, a feed roller, a separation roller which forms a separation nip portion with the feed roller, an encoder, and an engine control unit. The engine control unit obtains variation in rotation speed of the separation roller based on a detection result of the encoder, and determines a life condition of the separation roller based on the obtained variation in rotation speed of the separation roller.
