Abstract

The invention provides a toner container and an image forming apparatus. The toner container of the present invention has a container main body, a conveyance member, and a transmission member. The container main body accommodates toner and has a toner discharge port. The transport member rotates around a rotation shaft extending in a direction of the rotation shaft, and transports the toner in the container main body to the discharge port. The transmission member transmits rotation to the conveying member. The conveying member is configured to be able to move relative to the transmission member along the direction of the rotation axis between a connection position and a release position, wherein the connection position is a position where the conveyance member is connected to the transmission member; The release position is a position where the connection between the conveyance member and the transmission member is released. According to the present invention, when the used toner container is collected, it is possible to reliably prevent the toner from leaking from the discharge port of the container main body.

Description

technical field [0001] The present invention relates to a toner container and an image forming apparatus having the same. Background technique [0002] An image forming apparatus such as a copier or a printer that forms an image on paper by electrophotography has a developing device. A developer containing toner is housed inside the developing device. The developing device develops an electrostatic latent image formed on an image carrier such as a photosensitive drum with toner contained in a developer. By developing, the toner inside the developing device decreases. For this reason, the image forming apparatus has a toner container containing toner, and supplies toner from the toner container to the developing device. In addition, the toner container is detachably attached to a mounting portion provided in the image forming apparatus, and when the toner in the toner container becomes empty, it is replaced with a new toner filled with toner. container. [0003] For exam...
