Abstract

A drive transmission device includes a clutch mechanism. The clutch mechanism includes a drive transmission member that is coupled to a first rotation member via a torque limiter and is arranged in a fitting part of a second rotation member and a third rotation member, and a transmission member moving part that includes a first gap and a second gap, the first gap being formed in the fitting part and having a width wider than the thickness of the drive transmission member and the second gap being formed in the fitting part and having a width that is equal to or smaller than the thickness of the drive transmission member, the transmission member moving part being formed in such a way that the width thereof becomes smaller about a rotation axis in the fitting part.
