A driving-force transmission member includes a coupling portion that includes a driving-force transmission surface and that transmits a driving force to a cartridge coupling, a first helical gear portion that engages with a driven gear of a cartridge to transmit the driving force, and a second helical gear portion that engages with a drive gear to receive the driving force. The portions rotate integrally with each other when the driving-force transmission member rotates about the axis of rotation. The driving-force transmission surface is shaped with a twist in the same direction as the driving-force transmission member. Helical teeth of the first helical gear portion are shaped with a twist in the same direction as the driving-force transmission surface. Helical teeth of the second helical gear portion are shaped with a twist in a direction opposite to the twist direction of the helical teeth of the first helical gear portion.

A second energy storage has a second capacity deterioration factor which has a fluctuation with respect to a state of charge larger than a fluctuation of a first capacity deterioration factor. Circuitry is configured to control a converter to discharge one of the first energy storage and the second energy storage to charge another of the first energy storage and the second energy storage alternately when first temperature of the first energy storage and second temperature of the second energy storage are equal to or lower than a temperature threshold. The circuitry is configured to determine which of the first energy storage and the second energy storage is controlled to be discharged first based on the state of charge of the second energy storage, before the circuitry starts controlling the converter.
