Abstract: An example toner cartridge includes a housing to contain toner and having a toner outlet, a conveying member, a shutter to open and close the toner outlet, a driven coupler to rotate the conveying member and having an extension that extends in an axial direction, and a protruding member including a rotational force receiver installed in the extension so as to move to a protruding position in which the rotational force receiver protrudes from the extension and a retracted position in which the rotational force receiver is received into the extension in conjunction with opening and closing operations of the shutter.

Abstract: In some examples, a developing device includes a developing container including an opening and to store a developer, a developing sleeve installed in the developing container and partially exposed to an outside of the developing container through the opening, a regulation member upstream of the opening in a rotation direction of the developing sleeve and to regulate an amount of the developer adhered to the developing sleeve and supplied to the opening, and a magnetic member inside the developing sleeve. The magnetic member includes a main pole facing the opening, a regulation pole facing the regulation member, and a catch pole upstream of the regulation pole in the rotation direction of the developing sleeve. The magnetic member is to cause adhesion of the developer in the developing container to the developing sleeve. At least one of lengths of the catch pole or the regulation pole and diameters of both end portions of the catch pole or the regulation pole are less than a length and a diameter, respectively, of the main pole.

Abstract: An example toner cartridge includes a housing to accommodate toner and having a toner discharge port at one side, a conveying member inside the housing to rotate to convey the toner toward the toner discharge port, a driven coupler to rotate by a rotational force, and an ejector to rotate by the driven coupler. Either one of the driven coupler and the ejector is rotatably supported by a side wall of the housing in the longitudinal direction and connected to the conveying member to rotate the conveying member. The other one of the driven coupler and the ejector moves in a direction spaced apart from the side wall with respect to either one of the driven coupler and the ejector when the driven coupler rotates in a reverse direction which is an opposite direction to a forward direction in which the toner is conveyed toward the toner discharge port.
