摘要： A toner container includes a container body that is used to house a toner and that is detachably attachable to a mounting portion in a developing device; and an operating member that is used to open and close a shutter. The shutter as well as the operating member includes an engaging portion that can engage with a linking member which is disposed in the mounting portion and which can perform a reciprocating linear movement. In the state in which the container body is not mounted in the mounting portion, the shutter and the operating member are in a non-linked state with each other. In contrast, in the state in which the container body is mounted in the mounting portion, the shutter and the operating member become able to be linked to each other via the linking member.
