ABSTRACT:
A feeding apparatus including a feeding roller for conveying a sheet, a separation roller for conveying the sheet in a reverse direction, a transmission mechanism for transmitting the rotational force to the feeding roller, a limited force reverse transmission mechanism for transmitting the rotational force to the separation roller through a torque limiter, a forced reverse transmission mechanism for directly transmitting the rotational force to the separation roller, a temperature detector and a controller, wherein the controller controls the separation roller to receive rotational force through the forced reverse transmission mechanism after the limited force reverse transmission mechanism transmits the rotational force to the separation roller, then allows the limited force reverse transmission mechanism to transmit the rotational force to the separation roller, or to rotate the feeding via the transmission mechanism and the limited force transmission mechanism to transmit the rotational force to the separation roller.
