Image-forming device, in which holder unit detachably holding toner box is movably mounted

摘要

An image forming device includes a casing, a holder member, and a plurality of toner boxes. The holder member moves between an accommodated position in which it is accommodated in an accommodation space in the casing and a pull-out position in which at least part of the holder member is outside the accommodation space. Each toner box comprises a toner container formed with an opening and a shutter for opening and closing the opening. The operation member moves between a first position and a second position for closing and opening the shutter, respectively. When the holder member is on its way to the accommodated position from the pull-out position, a stop member prevents the holder member from moving while the operation member is at the first position and permits the holder member to move while the operation member is at the second position.
