Summary: | PROBLEM TO BE SOLVED: To provide a drive transmission device that can satisfactorily suppress a change in angular velocity, and an image forming apparatus including the drive transmission device.SOLUTION: A drive transmission device 70 comprises: a first rotator, such as a photoreceptor gear 82 that includes a hole part in the center of rotation; a second rotator, such as a coupling member 41 that includes a hole part in the center of rotation; and a connection member 90 that has a first insertion part, such as a drive-side spherical part 91 that is inserted into the hole part of the first rotator, a second insertion part, such as a driven-side spherical part 92 that is inserted into the hole part of the second rotator, and a connection part 93 connecting the first insertion part and second insertion part, and connects the first rotator and second rotator. The insertion parts have columnar-shape projections 94a, 94b, and 95a projecting in the radial direction, respectively on their peripheral surfaces.SELECTED DRAWING: Figure 2
