A method of converting a CMYW toner printer to a CMYK printer that prints with black toner, comprising the steps: providing a CMYW toner printer; wherein the CMYW toner printer has four starting toner printing cartridges; wherein the four starting toner printing cartridges comprise a white toner printing cartridge, a cyan toner printing cartridge, a magenta toner printing cartridge, and a yellow toner printing cartridge; removing one or more of the four starting toner printing cartridges from the CMYW toner printer, such that there are one or more empty toner cartridge slots; providing a black toner printing cartridge that are each filled with black toner; and installing the black toner printing cartridge into the one or more empty toner cartridge slots.

The present disclosure features an image forming apparatus having a first developing unit having a first developing roller; and a first toner supply unit configured to supply toner to the first developing unit, the first toner supply unit having: a first container configured to accommodate the toner therein, the first container having a first inlet opening through which the toner is received in the first container and a first outlet opening through which the toner in the first container is discharged; a first lid configured to close the first inlet opening; and a first shutter configured to open the first outlet opening when the first lid closes the first inlet opening, and to close the first outlet opening when the first lid opens the first inlet opening.

A remanufacturing method of a developing apparatus including: a communicating step of removing a part of a frame of the developing apparatus to form a communication hole such that an outside of the frame and a developing chamber of the frame are connected each other; a refilling step of refilling an inside of the frame with developer via the communication hole; and a sealing step of sealing the communication hole.

A method of remanufacturing a toner cartridge includes obtaining a toner cartridge including a drive transmitting gear supported for rotation by an axle oriented substantially perpendicularly relative to a side surface of the cartridge. The drive transmitting gear includes an overhanging flange portion that faces and is spaced from the side surface of the cartridge to define an open space between the side surface and the overhanging flange portion. A supplemental support member may be positioned into the open space. The supplemental support member is configured to limit movement of the overhanging flange portion toward the side surface.

A method of converting a CMYW toner printer to print with one or more non-standard toners, comprising the steps: providing a CMYW toner printer; wherein the CMYW toner printer has four starting toner printing cartridges; wherein the four starting toner printing cartridges comprise a white toner printing cartridge, a cyan toner printing cartridge, a magenta toner printing cartridge, and a yellow toner printing cartridge; removing one or more of the four starting toner printing cartridges from the CMYW toner printer, such that there are one or more empty toner cartridge slots; providing one or more non-standard toner printing cartridges that are each filled with one type of one or more non-standard toners; and installing the one or more non-standard toner printing cartridges into the one or more empty toner cartridge slots.

Discloses herein is a storage component disassembly tooling, which can be used to disassemble a storage component on a process cartridge. The process cartridge comprises a housing and a storage component mounting bracket provided on the housing for supporting the storage component. The storage component disassembly tooling comprises: a drilling portion; and a positioning portion, wherein the positioning portion can position the storage component disassembly tooling on the housing of the process cartridge, and the drilling portion can be drilled into the storage component mounting bracket and destroy at least a part of the storage component mounting bracket. The storage component disassembly tooling not only has simple operation, shortens the disassembly time of the storage component, improves the disassembly efficiency, and saves time and labor. Moreover, the storage component disassembly tooling has a relatively simple structure, and the manufacturing difficulty and manufacturing cost are relatively low.
