Embodiment Construction

[0030] Exemplary embodiments of the present invention are described in detail below with reference to the accompanying drawings. The invention is not limited to these exemplary embodiments.

[0031] figure 1 is a schematic diagram of an image forming apparatus 1 such as a color printer according to an embodiment of the present invention. The image forming apparatus 1 includes four image forming units 6Y, 6M, 6C, and 6K that form yellow, magenta, cyan, and black toner images, respectively. The exposure unit 5 is disposed above the imaging units 6Y, 6M, 6C, and 6K. The exposure unit 5 exposes the photosensitive drum in each of the image forming units 6Y, 6M, 6C, and 6K to form an electrostatic latent image on the photosensitive drum. The intermediate transfer belt 3 extends horizontally around a plurality of support rollers below the image forming units 6Y, 6M, 6C, and 6K. The secondary transfer unit 11 and the belt cleaning unit 14 are arranged on the right side of the inte...

Abstract

The present invention discloses a toner cartridge, a process cartridge and a method of making toner cartridge reusable. The toner cartridge is configured by integrally arranging a fresh toner storing chamber and a residual toner collection chamber. Fresh toner is filled in the fresh toner storing chamber through a fresh toner filling opening. Residual toner is conveyed in the residual toner collection chamber through a residual toner conveying opening. Two residual toner discharging openings are created in the residual toner collection chamber through which the residual toner is discharged.

Description

technical field [0001] The present invention relates to a technique for enabling repeated use of a toner cartridge in an image forming apparatus. Background technique [0002] An imaging device includes a number of consumable imaging components, such as an image bearing member and a developing unit. The developer unit consists of rotatable components, such as the developer roller and agitation screw, that experience wear and tear through frequent exposure to imaging light. Furthermore, the amount of developer (one-component developer or two-component developer) in the developing unit or the toner concentration in the developer decreases with time. Thus, frequent replenishment of developer or toner is required. For this reason, it has been proposed to automate the process of toner filling or the process of replacing the toner carrier. [0003] In the early days, a skilled worker had to be relied upon to replace a worn image bearing member or developing unit from an imaging...
