IMAGE-FORMING DEVICE, IN WHICH HOLDER UNIT DETACHABLY HOLDING TONER BOX IS MOVABLY MOUNTED

摘要

An image forming device includes: a main casing; a holder member; a plurality of image bearing members; a plurality of developing units; a plurality of toner boxes; an operation member; and a stop member. The main casing defines an accommodation space. The holder member is configured to be movable in a moving direction between an accommodated position in which the holder member is accommodated in the accommodation space and a pull-out position in which at least part of the holder member is outside the accommodation space. The plurality of image bearing members are held by the holder member and are juxtaposedly arrayed in the moving direction with intervals between neighboring image bearing members. The plurality of developing units are held by the holder member in one to one correspondence with the plurality of image bearing members. The plurality of toner boxes are detachably attachable to the holder member in one to one correspondence with the plurality of developing units. Each toner box is detachably attachable to the holder member at the pull-out position. Each toner box includes: a toner container accommodating toner therein and formed with an opening, through which toner in the toner container is to be supplied to the corresponding developing unit; and a shutter movable between an open position for opening the opening and a closed position for closing the opening. The operation member is configured to be movable between a first position providing the closed position of the shutter and a second position providing the open position of the shutter. The stop member is provided in the main casing and configured to prevent the holder member from moving when the holder member is on its way to the accommodated position from the pull-out position while the operation member is at the first position.
