Drive transmission device, drive unit, and image forming apparatus

Abstract

To provide a drive transmission device, drive unit and image formation apparatus which can enhance the assembling workability to a device body.SOLUTION: A drive transmission device 30 includes a drive train constituted by a plurality of drive transmission members that transmit the driving force of a fixation motor as a drive source to a changeover claw as an oscillation member provided in an oscillatable manner and a sheet discharge inversion drive roller as a rotor. The plurality of drive transmission members constituting the drive train are stored in a housing 31 as a storage member. The housing 31 is attached to a rear plate of the device.SELECTED DRAWING: Figure 4
