Embodiment Construction

[0040] figure 1 Shown is a process cartridge 10 according to a first embodiment of the present invention. The processing cartridge 10 includes a first positioning element 12 and a second positioning element 14 respectively disposed at two ends in the longitudinal direction thereof. The following processing elements are extended between the first positioning element 12 and the second positioning element 14: photosensitive drum 16, developing roller 18, triboelectric blade (not shown), cleaning blade (not shown) and charging roll 20. In addition, the following housing elements are disposed between the first positioning element 12 and the second positioning element 14 : a toner cartridge 26 and a toner recovery unit 28 . Finally, a support plate 70 is removably connected to the first positioning element 12 , and there may be a second support plate (not shown) also removably connected to the second positioning element 14 .

[0041] The charging roller 20 is rotatable, and a sha...

Abstract

A process cartridge (10) detachably mountable for an image apparatus comprises a pair of locating elements and at least one supporting element (70). Each locating element (12, 14) is provided with a plurality of holes (40, 42). The at least one supporting element (70) is provides with a plurality of locating parts (72, 74) used to be contained in the at least one hole (40, 42) on the corresponding locating elements (12, 14). Each locating part (72, 74) is provided with a hole. Therefore, when the at least one supporting element (70) is stably contained in a first hole (40) and a second hole (42) of the corresponding locating elements (12, 14) and a rotating photosensitive drum (16) is at least partially contained in the first hole (40) of the locating part (72), a rotating developer roller (18) is at least partially contained in the second hole (42) of the locating part (74), the holes of the locating parts (72, 74) can limit the side displacement of the rotating photosensitive drum (16) and the rotating developer roller (18) during the operation of the process cartridge (10).

Description

technical field [0001] The present invention relates to a processing box composed of two positioning components, a photosensitive drum and at least one processing component, wherein the photosensitive drum and the processing component are extended between the two positioning components. More specifically, the process cartridge is detachably mounted on an imaging device. Background technique [0002] The following description of the background of the present invention is to help clarify the present invention, and does not mean that the applicant acknowledges that the prior art referred to below is a fact that was published, disclosed or common knowledge in any region at the time of the priority date of this application. [0003] The main function of a household or commercial printing system is to print images and texts on media such as paper. These systems mainly include two components, namely a printer and a processing cartridge. Generally speaking, the process cartridge is...
