<p>In order to reduce costs and fulfill a desired function by reliably preventing erroneous attachment to a shaft, disclosed is a rotation restricting member provided with a shaft insertion hole (1) which is set to have a shape corresponding to the shape of a rotation shaft (b1, b2) of a rotation shutter of a toner container (B1, B2) and into which the rotation shaft (b1, b2) is inserted in a predetermined posture relationship, and a plurality of lock holes (2a, 2b) each of which is formed at a different position around the shaft insertion hole (1) and fulfills a rotation lock function by engaging with a protrusion (b3, b4) of the toner container (B1, B2). The shaft insertion hole (1) is attached around the rotation shaft (b1, b2) at a different angle according to the shape of the rotation shaft (b1, b2), thereby allowing the engagement of any of the plurality of lock holes (2a, 2b) with the protrusion (b3, b4).</p> |
