ABSTRACT:
A transmission device includes a rotation shaft, a gear coaxially fixed to the rotation shaft by press-fitting, and a restriction member fixed to the rotation shaft for restricting perpendicularity of the gear to the axial line of the rotation shaft by pressing in contact with one end face of the gear so as to transmit the rotation of the driven gear onto the rotation shaft for rotating a photosensitive drum fixed to the rotation shaft. The rotation shaft can be fitted into a mounting hole of the gear with a small force so as to improve efficiency in assembling these components.
