Abstract:
1. A developing mechanism for development with developer in a main housing, the developing mechanism comprising: a developing device configured to supply the developer to an electrostatic latent image and develop the electrostatic latent image; and a container configured to contain the developer and to be inserted into the main housing, wherein the developing device includes: the container includes: the second shutter mechanism includes a second shutter member that is displaced between a second closing position for closing the supply port and a second opening position for opening the supply port, and a first protrusion that protrudes from the second shutter member, and the second housing includes a protruding tongue that protrudes in the second direction so as to hit and displace the first shutter ember to the first opening position before the first protrusion hits the edge, the first protrusion is configured to displace the second shutter member from the second closing position to the second opening position to make the supply port communicate with the feed port, characterized in that the protruding tongue and the first protrusion are configured to cause displacement of the second shutter member from the second closing position to the second opening position after arrival of the first shutter member at the first opening position.
