본 발명은 전자사진 프로세서에 관한 것으로서, 특히 2성분 현상방식을 이용한 현상기에 있어서의 토너공급 제어장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrophotographic processor, and more particularly, to a toner supply control apparatus in a developing device using a two-component developing method.

도 1은 2성분 현상방식에 따른 현상기의 내부 구조를 나타낸 개략도이다.1 is a schematic diagram showing an internal structure of a developing device according to a two-component developing method.

2성분 현상방식에 따른 현상기는 도 1에 도시된 바와 같이 토너(65)를 적재하고 일측에 토너공급구를 구비한 토너적재부(10)와, 상기 토너적재부의 내측에는 양단에 필름이 부착된 호퍼(50)와, 상기 토너적재부의 토너공급구를 막도록 부착된 토너필름(18)과, 상기 토너공급구 외측에 설치된 공급롤러(40)와, 상기 공급롤러의 타측에 형성한 현상실(35)과, 상기 현상실 내측에 설치된 현상롤러(30)와, 상기 현상롤러의 타측에 형성되어 현상제(60)를 적재하고 현상제공급구를 구비한 현상제적재부(20)와, 상기 현상제공급구를 막도록 설치된 현상제필름(28)으로 구성된다.The developing device according to the two-component developing method, as shown in FIG. 1, has a toner 65 loaded with a toner supply port on one side thereof, and a film is attached to both ends inside the toner loading part. A hopper 50, a toner film 18 attached to block the toner supply port of the toner loading portion, a supply roller 40 provided outside the toner supply port, and a developing chamber formed on the other side of the supply roller ( 35), a developing roller 30 provided inside the developing chamber, a developer loading part 20 formed on the other side of the developing roller, having a developer 60 loaded therein, and having a developer supply port; It consists of a developer film 28 installed to block the supply port.

상기와 같이 구성된 현상기의 작동과정을 설명하면 다음과 같다.Referring to the operation of the developing device configured as described above are as follows.

상기 현상기(100)를 전자사진 프로세서의 본체에 장착하고, 상기 현상제필름(28)과 토너필름(18)을 제거한다. 그러면, 상기 현상롤러(30)의 회전에 의해 현상제(60)가 현상롤러(30) 표면에 도포되고, 상기 토너(65)는 호퍼(50)의 회전에 의해 공급롤러(40) 표면에 도포되고, 공급롤러 표면의 토너는 상기 공급롤러의 회전에 의해 현상롤러가 위치한 현상실(35)로 공급된다. 이어, 현상실로 공급된 토너는 현상롤러(30)의 표면에 도포된 현상제와 섞여 현상롤러 표면에 입혀진다.The developer 100 is mounted on the main body of the electrophotographic processor, and the developer film 28 and the toner film 18 are removed. Then, the developer 60 is applied to the surface of the developing roller 30 by the rotation of the developing roller 30, and the toner 65 is applied to the surface of the feed roller 40 by the rotation of the hopper 50. Then, the toner on the surface of the feed roller is supplied to the developing chamber 35 in which the developing roller is located by the rotation of the feed roller. Then, the toner supplied to the developing chamber is mixed with the developer applied to the surface of the developing roller 30 and coated on the surface of the developing roller.

한편, 상기와 같은 롤러와 호퍼의 구동은 현상기 외측에 설치된 구동기어부에 의해서 가능한데 이는 도 2에 도시된 바와 같다. 도 2는 종래의 실시예에 따른 현상기 구동기어부를 나타낸 측면도이다.On the other hand, the driving of the roller and the hopper as described above is possible by the drive gear installed on the outside of the developer, as shown in FIG. 2 is a side view showing a developer driving gear part according to a conventional embodiment.

현상기의 구동기어부는 현상롤러축과 결합한 현상롤러기어(71)와, 상기 현상롤러기어와 맞물린 연결기어(72)와, 상기 연결기어에는 직경이 큰 내측기어와 맞물리고 외측에는 직경이 작은 외측기어가 형성된 제1감속기어(73)와, 상기 제1감속기어의 외측기어와 맞물리고 중앙이 공급롤러축(81)과 결합된 공급롤러기어(74)와, 상기 공급롤러기어에는 직경이 큰 내측기어와 맞물리고 외측에는 직경이 작은 외측기어가 형성된 제2감속기어(75)와, 상기 제2감속기어의 외측기어와 맞물리고 중앙이 호퍼축(82)과 결합된 호퍼기어(76)로 이루어진다.The driving gear of the developing machine is a developing roller gear 71 coupled with a developing roller shaft, a connecting gear 72 meshed with the developing roller gear, and an outer gear having a small diameter on the outside thereof in engagement with a large inner diameter of the connecting gear. Is provided with a first reduction gear 73, a feed roller gear 74 engaged with an outer gear of the first reduction gear, the center of which is combined with a feed roller shaft 81, and the inside of the feed roller gear having a large diameter. And a second reduction gear 75 having an outer gear having a small diameter on the outside thereof, and a hopper gear 76 engaged with the outer gear of the second reduction gear and having a center thereof coupled with the hopper shaft 82. .

도 3은 종래의 실시예에 따른 공급롤러기어가 공급롤러기어축에 장착된 모습을 나타낸 단면도이다. 도 3에 도시된 바와 같이 공급롤러기어(74)는 공급롤러기어축의 단부가 공급롤러기어의 중앙에 형성한 반달 모양의 구멍에 삽입되므로써 공급롤러기어축(81)과 결합된다. 호퍼기어(76) 역시 공급롤러기어와 같이 호퍼기어축의 단부가 호퍼기어의 중앙에 형성한 반달 모양의 구멍에 삽입되므로써 호퍼기어축(82)과 결합한다.3 is a cross-sectional view showing a state in which a feed roller gear is mounted on a feed roller gear shaft according to a conventional embodiment.

그러나, 위와 같은 방법을 사용할 때 상기 현상롤러기어가 회전하면 공급롤러기어 및 호퍼기어가 연속적으로 회전한다. 즉, 현상기의 구동기어부에는 단속되는 곳이 없으므로 상기 현상롤러 표면에 현상제가 완전히 도포되기도 전에 토너적재부의 토너가 현상실 내부로 유입되어 현상롤러에 묻게 되고, 이러한 현상롤러 표면의 토너 농도변화로 인해 화상품질이 저하되는 문제점이 있었다.However, when the developing roller gear rotates when the above method is used, the feed roller gear and the hopper gear rotate continuously. That is, since there is no interruption in the driving gear part of the developing machine, the toner in the toner loading part is introduced into the developing chamber and is buried in the developing roller before the developer is completely applied on the surface of the developing roller. There was a problem that the image quality is reduced.

상기와 같은 문제점을 해결하기 위하여 본 발명의 목적은 2성분 현상방식의 현상기에 있어서, 현상롤러 표면에 현상제가 도포된 후 현상롤러에 토너가 공급될 수 있도록 토너공급시기를 조절하는 토너공급 제어장치를 제공하는데 있다.In order to solve the above problems, an object of the present invention is a toner supply control device for adjusting a toner supply time so that toner can be supplied to a developing roller after a developer is coated on a developing roller surface in a two-component developing method.
