To minimize uneven rotation of a rotation body.SOLUTION: A drive transmission device comprises: a first gear; and a second gear meshing with the first gear for transmitting drive to the rotation body via the first gear and the second gear. All teeth of the first gear and the second gear include: between the tooth tip and the tooth bottom, one tooth surface on the meshing side; and the other tooth surface on the non-meshing side opposite to the one tooth surface. The one tooth surface is a surface formed to along an involute curve; and the other tooth surface is a surface that provided on the inside of the line symmetry one tooth surface based on a straight line passing through the tooth tip from the center of rotation of the gear, and that passes the straight line between the tooth tip and the tooth bottom.SELECTED DRAWING: Figure 1 【課題】回転体の回転ムラを小さく抑えること。【解決手段】第一歯車と、前記第一歯車と噛み合う第二歯車と、を備え、前記第一歯車と前記第二歯車を介して回転体に駆動を伝達する駆動伝達装置であって、前記第一歯車および前記第二歯車の全ての歯は、歯先と歯底の間において、噛み合う側の一方の歯面と、前記一方の歯面とは反対側で非噛み合い側の他方の歯面と、を有し、前記一方の歯面は、インボリュート曲線に沿うように形成された面であり、前記他方の歯面は、歯車の回転中心から歯先を通る直線を基準とした前記一方の歯面の線対称な面より内側に設けられた、歯先から歯底まで前記直線を通る面である。【選択図】 図１
