Abstract:
A drive device, which is included in an image forming apparatus, includes a drive source, an input side rotary body, an output side rotary body, two drive transmission routes, a drive transmission state switcher, and a drive transmission changer. The input side rotary body receives a driving force from the drive source. The output side rotary body outputs the driving force to a driving target body. The drive transmission state switcher switches a first drive transmission route between a transmission state and a non transmission state. The drive transmission changer transmits the driving force via a second drive transmission route to the output side rotary body when the first drive transmission route is in the non transmission state and restricts the driving force from being transmitted via the second drive transmission route when the first drive transmission route to the output side rotary body is in the transmission state.

Claim (Index 13):
A drive device comprising:\n a drive source configured to exert a driving force; an input side rotary shaft rotatably disposed and configured to receive the driving force from the drive source; an output side rotary shaft rotatably disposed and configured to transmit the driving force to a driving target body configured to rotate in a forward direction or a reverse direction opposite to the forward direction; a first drive transmission route configured to transmit the driving force from the input side rotary shaft to the output side rotary shaft if the driving target body is rotated in the forward direction; and a second drive transmission route configured to transmit the driving force from the input side rotary shaft to the output side rotary shaft if the driving target body is rotated in the reverse direction, the second drive transmission route including an electromagnetic clutch configured to switch the second drive transmission route between a transmission state in which the driving force is transmitted and a non-transmission state in which transmission of the driving force is cut off, wherein the first drive transmission route includes a torque limiter configured to,\n transmit the driving force via the first drive transmission route to the output side rotary shaft if the second drive transmission route is in the non transmission state, and \n restrict the transmission of the driving force from the first drive transmission route to the output side rotary shaft if the second drive transmission route is in the transmission state.
