Patent ID: 8750751

Claim:
An image forming apparatus comprising: an image carrier on which a latent image is formed; a developing device that develops the latent image formed on the image carrier with a toner; a toner container that contains toner to be supplied and that is attached to a container support member by being moved in an attachment direction and detached from the container support member by being moved in a detachment direction that is opposite to the attachment direction; the container support member that supports the toner container that has been attached to the container support member; a toner supply unit that supplies the toner contained in the toner container to the developing device in accordance with consumption of the toner in the developing device; a transfer device that transfers the toner image on the image carrier onto a recording medium; a fixing device that fixes the toner image that has been transferred onto the recording medium to the recording medium; and a restricting mechanism, wherein the toner container includes a container housing having a container opening through which the toner in the toner container is discharged, a sealing member that is elastic and has a hole that communicates with the container opening, the sealing member being disposed in an area surrounding the container opening, and a shutter member that is slidable between a closed position at which the shutter member closes the container opening and an open position at which the shutter member opens the container opening and at which a front end portion of the shutter member in the attachment direction at least partially overlaps with the sealing member, the shutter member being moved to the open position when the toner container is attached to the container support member, the front end portion being pressed toward a direction away from the toner container by the sealing member when the front end portion partially overlaps with the sealing member, wherein the container support member has a support-member opening that is located so as to communicate with the container opening in the toner container when the toner container is attached to the container support member, and wherein when the shutter member is at the open position, the front end portion is pressed in a direction away from the toner container by the sealing member, and the restricting mechanism restricts a position of a back end portion of the shutter member, the back end portion being opposed to the front end portion.
