Abstract: A printer includes a main body including a printing unit for printing an image, a developer cartridge for accommodating a developer to be supplied to the printing unit and removable from the main body, a releasing member provided in the main body and pushing the developer cartridge in a removal direction to move the developer cartridge from a mounting position where the developer cartridge is locked to the main body to a removal position where the developer cartridge is unlocked, and a handle provided on the developer cartridge. The handle moves in conjunction with the movement of the developer cartridge from the mounting position to the removal position of the developer cartridge such that the handle is switched from a first position adjacent to a side of the developer cartridge to a second position protruding from the side of the developer cartridge, so that the handle can be gripped.

Abstract: A toner container is detachably attachable to a developing device. The toner container includes an outlet to discharge toner contained in the toner container, an agitating member to agitate the toner in the container, a coupling to transmit a driving force to the agitating member, a shutter to open and close the outlet, a lever disposed at one end of the container and a pivoting portion disposed at the other end and connected by a common shaft such that both rotate together, and the lever and the coupling are disposed at the one end in a mutually non-overlapping manner when viewed from the axial direction of the common shaft.

Abstract: A toner container includes a container body that is used to house a toner and that is detachably attachable to a mounting portion in a developing device; and an operating member that is used to open and close a shutter. The shutter as well as the operating member includes an engaging portion that can engage with a linking member which is disposed in the mounting portion and which can perform a reciprocating linear movement. In the state in which the container body is not mounted in the mounting portion, the shutter and the operating member are in a non-linked state with each other. In contrast, in the state in which the container body is mounted in the mounting portion, the shutter and the operating member become able to be linked to each other via the linking member.

Abstract: Provided is a toner recycling device for an image forming apparatus, including a waste toner conveying screw which conveys waste toner collected out of a surface of a photosensitive drum to one side; a toner recycling means which is connected with the waste toner conveying screw to be rotated by rotation of waste toner conveying screw, filters a foreign substance out of the waste toner conveyed by the waste toner conveying screw, supplies the recycled toner from which the foreign substance is removed toward a developing unit, and discharges the foreign substance filtered out of the waste toner to an outside of a drum unit; and a collecting case which is integrally formed with the drum unit at one side of the drum unit to collect the foreign substance filtered by the toner recycling means, wherein the foreign substance like paper dust contained in the waste toner is filtered, and then the recycled toner is supplied again toward the developing unit, thus it is possible to prevent the quality of a printed image

Abstract: Disclosed is a developer discharging device for an image forming apparatus, which is installed in a developing unit configured to transfer and discharge a developer collected from a drum unit or a newly introduced developer, such that the developer is discharged to a developer collecting unit, including a first discharging part configured to extend from an end of a transferring screw installed in the developing unit, and a second discharging part disposed above the first discharging part in parallel with the first discharging part, wherein the developer discharged from the second discharging part falls into the developer collecting unit. Therefore, it is possible to prevent the developer from being sharply discharged, and thus to constantly maintain an amount of the developer.
