摘要： A driving-force transmission member (81) includes a coupling portion (81b) that transmits a driving force to a cartridge coupling (63b), a first helical gear portion (81a) that engages with a driven gear (30a) of a cartridge (B) to transmit the driving force, and a second helical gear portion (81e) that engages with a drive gear (105) to receive the driving force. The portions (81b, 81a, 81e) rotate integrally 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.

The portions (81b, 81a, 81e) rotate integrally 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.
