IMAGE FORMING APPARATUS AND TONER CONTAINER ATTACHABLE TO AND DETACHABLE FROM IMAGE FORMING APPARATUS

摘要

In the structure of a shutter moving mechanism, if the inclination angle of an elongated hole with respect to a sliding direction of a shutter is increased, it is necessary to increase the size of a movement plate for moving the shutter. On the other hand, if the inclination angle of the elongated hole with respect to the sliding direction of the shutter is decreased, an urging force with which a user urges the door against an image forming apparatus when shutting the door is increased.;A shutter moving mechanism includes a rotation mechanism and moves the shutter by rotation of the rotation mechanism.

主权项

1. An image forming apparatus comprising:
a plurality of photoconductor members and a plurality of developing devices that develop electrostatic latent images, which are formed on the plurality of photoconductor members, by using toner; an optical scanning device including transparent windows through which light beams pass, the light beams scanning the plurality of photoconductor members to form the electrostatic latent images on the plurality of photoconductor members; a shutter that is disposed between the plurality of photoconductor members and the optical scanning device and that moves between a first position at which the shutter is withdrawn from optical paths of the light beams that have passed through the transparent windows and a second position at which the shutter covers the transparent windows; an intermediate transfer member to which toner images on the photoconductor members are transferred and a transfer device that transfers the toner images on the intermediate transfer member to a recording medium; a cleaning device that recovers residual toner that remains on the intermediate transfer member instead of being transferred to the recording medium; a toner container holding unit that holds a toner container for containing the residual toner recovered by the cleaning device, the toner container being attachable to and detachable from a body of the image forming apparatus and including a protruding portion; and a shutter moving mechanism including a first movement portion that moves around a rotation shaft as a rotation axis and a second movement portion that contacts the shutter and that moves around the rotation shaft as the rotation axis in accordance with movement of the first movement portion around the rotation shaft as the rotation axis, wherein, when the toner container is attached to the toner container holding unit, the first movement portion contacts the protruding portion of the toner container before the toner container is held by the toner container holding unit, the first movement portion in contact with the protruding portion and the second movement portion move around the rotation shaft as the rotation axis in a first direction in accordance with movement of the toner container, and thereby the second movement portion moves the shutter from the second position to the first position.
