Rotary body driver with planetary gear transmission and image forming apparatus incorporating same
A rotary body driver includes a driving source and a planetary gear transmission to receive a driving force from the driving source. The planetary gear transmission includes a sun gear rotatable by the driving force received from the driving source, a plurality of planet gears meshed with and surrounding the sun gear with an identical interval between the adjacent planet gears, a rotatable carrier to rotatably support the plurality of planet gears, an outer gear encircling and meshed with the plurality of planet gears, and an output shaft combined with and supporting the carrier. A rotary body shaft mounting a rotary body is connected to the output shaft of the planetary gear transmission to transmit the driving force received from the output shaft to the rotary body. The outer gear is made of resin and the output shaft and the carrier are made of metal.
