摘要： A device is to supply printing material to a printing material container in a printing apparatus. The device includes a first container to contain printing material, a first piston movable in the first container to exert first pressure to discharge the printing material contained in the first container from the first container, a second container having an opening to the first container, and a second piston movable in the second container to exert second pressure higher than the first pressure to form a pressure gradient based on the first pressure and the second pressure through the opening. The pressure gradient is to disperse the printing material in the first container.

摘要： An image forming apparatus includes an image forming portion, a supply processing portion, and a second release processing portion. The image forming portion includes a storing portion that stores developer, and forms an image by using the developer stored in the storing portion. The supply processing portion supplies the developer to the storing portion from a developer storing portion attached to an attachment portion, when a storage amount of the developer in the storing portion is less than or equal to a first threshold. The second release processing portion releases regulation on a removal of the developer storing portion when an expected amount of developer to be used by a user is greater than or equal to a reference value that is determined based on a remaining amount of the developer in the developer storing portion attached to the attachment portion.

摘要： An imaging system includes: a housing including a developing chamber, a developing roller located in the developing chamber to transport a developer and spaced apart from the housing; a conveyance path extending along at least part of a periphery of the developing roller in order to form a flow of air including the developer; and a control member. The developing roller includes a peeling pole at a fixed position with respect to the housing, to discharge the developer. The control member is located along the conveyance path in proximity to the peeling pole of the developing roller, to reduce a flow rate of the air flowing through the conveyance path.
