Abstract: A power transmission apparatus includes a drive source, a power transmission switching section configured to switch between a transmission state in which power of the drive source is transmitted to a driven section and a non-transmission state in which power of the drive source is not transmitted to the driven section, a load switching section configured to switch between a first load state, which is a load while the driven section is driven, and a second load state, which is a load smaller than the load of the first load state, and a control section, wherein the control section switches the power transmission switching section from the non-transmission state to the transmission state while the load is in the second load state, and then uses the load switching section to switch the load from the second load state to the first load state.

Abstract: An image forming apparatus includes: an image-forming mechanism; a reconveying roller; an electric motor; and a transmission mechanism. The transmission mechanism is configured to operate in one of a reverse-rotation transmission mode for reversing a direction of a rotational force received from the electric motor to transmit the reversed rotational force to the reconveying roller and a normal-rotation transmission mode for transmitting the rotational force to the reconveying roller without reversing the direction of the rotational force. The transmission mechanism includes an interrupting unit for interrupting transmission of a rotational force from the reconveying roller to the electric motor at least when a sheet is being conveyed in the image-forming mechanism. The transmission mechanism is configured to interrupt transmission of the rotational force received from the electric motor to the reconveying roller when a sheet is being conveyed in the image-forming mechanism.

Abstract: Torque is applied to a separation roller of an image processing apparatus when a leading edge of the sheet in a transport direction reaches a first transport roller and when the leading edge of the sheet in the transport direction reaches a transport unit. Torque to the separation roller is cut off after the leading edge of the sheet has reached the transport unit but before the leading edge of the sheet reaches the image processing unit.
