摘要： A drive transmission unit includes a planetary gear mechanism. The planetary gear mechanism includes an outer gear rotatably disposed on a shaft, a sun gear rotated by a power source, coaxially disposed on the same shaft as the outer gear, multiple planetary gears to engage the sun gear and the outer gear, disposed along an inner circumferential surface of the outer gear, a carrier rotatable on the same shaft as the outer gear to rotatably support the planetary gears, a contact member that contacts the sun gear as the sun gear moves in a direction of thrust due to engagement with the plurality of planetary gears, and a grease retaining portion to retain grease near a contact portion at which the sun gear contacts the contact member as the sun gear moves in the direction of thrust. The outer gear, the sun gear, and the planetary gears are helical gears.
