Abstract
A feeding apparatus includes a rotary member unit having a feeding rotary member to feed a recording material and a separating rotary member which forms a nip portion with the feeding rotary member, an output unit, and a control unit. Where a single recording material is fed to the nip portion, the separating rotary member is rotated in a predetermined direction by the single recording material and, where recording materials are overlapped with one another and fed to the nip portion, the separating rotary member rotation is stopped or rotated in a direction opposite to the predetermined direction to separate the overlapped recording materials. The output unit outputs a state signal in accordance with a separating rotary member rotation state. The control unit obtains a rotation speed of the separating rotary member from the state signal output and determines that the rotary member unit is replaced with a new product.
