A powder container includes a powder chamber for containing powder for forming images, a powder outlet formed in a face of the powder container, and a shutter assembly to open and close the powder outlet and including first and second shutters. The first shutter is movable between a sealing position to close the powder outlet and an open position to open the powder outlet and includes a pressed member to cancel retention of the first shutter at the sealing position. The second shutter includes a pressing projection that interferes with the pressed member of the first shutter and is movable between a shielding position to cover the pressed member without interference between the pressing projection and the pressed member and a releasing position to press the pressed member with the pressing projection.
