발명의 분야Field of invention

본 발명은 프린터의 토너 카트리지에 사용되는 전자 사진 감광체(organic photo conductor: "OPC") 드럼에 관한 것이다. 보다 구체적으로, 본 발명은 정대전 단층형 OPC 드럼에 사용되는 전자 사진 감광체 조성물 및 그 제조방법에 관한 것이다.The present invention relates to an organic photo conductor ("OPC") drum used in a toner cartridge of a printer. More specifically, the present invention relates to an electrophotographic photoconductor composition for use in a positively charged single-layer OPC drum and a method of manufacturing the same.

발명의 배경Background of the Invention

전자 사진 감광체가 형성된 OPC 드럼은 정대전(positive-charged) 단층형과 부대전(negative-charged) 적층형으로 구분된다. 이들 전자 사진 감광체는 모두 알루마이트 도금층이 형성된 알루미늄 파이프에 형성된다.OPC drums formed with electrophotographic photosensitive members are classified into positive-charged monolayers and negative-charged laminates. All of these electrophotographic photosensitive members are formed in an aluminum pipe on which an alumite plating layer is formed.

부대전 적층형 OPC 드럼은 알루마이트 도금층 위에 전하 발생재료로 이루어진 전하 발생층을 형성하고, 다시 전하 발생층 위에 전자 수송재료로 이루어진 전하 수송층을 형성한다. 그리고 OPC 드럼 내부에 ＋전하를 걸어주어 드럼 표면에 －전하가 형성되도록 한다. 부대전 2층형 OPC 드럼에서는 전하 발생층을 형성하기 위한 전하 발생재료 조성액과 전하 수송층을 형성하기 위한 전하 수송재료 조성액이 서로 각각 제조된다.The secondary charge stacked OPC drum forms a charge generating layer made of a charge generating material on the alumite plating layer, and further forms a charge transport layer made of an electron transporting material on the charge generating layer. Then, + charge is applied to the inside of the OPC drum so that-charge is formed on the drum surface. In the incident charge two-layer type OPC drum, the charge generating material composition liquid for forming the charge generating layer and the charge transport material composition liquid for forming the charge transport layer are respectively prepared.

정대전 단층형 OPC 드럼은 전하 발생재료와 전하 소송재료를 함께 혼합한 감광체 조성액을 제조하고, 그 감광체 조성액을 알루마이트 도금층 위에 단층으로 코팅하여 제조한다. 정대전 단층형 OPC 드럼은 드럼 내부에 －전하를 걸어주어 드럼 표면에 ＋전하가 형성되도록 한다.The positively charged single-layer OPC drum is prepared by preparing a photoconductor composition liquid in which a charge generating material and a charge lawsuit material are mixed together, and coating the photoconductor composition liquid as a single layer on the alumite plating layer. The positively charged single-layer OPC drums impose negative charges on the drums so that positive charges form on the drum surface.

그런데 정대전 단층형 전자 사진 감광체 조성물은 안정성이 좋지 못한 결점이 있다. 여기서 감광체 조성물의 액 안정성이 좋지 못하다는 것은 전하 발생재료와 전하 수송재료가 함께 혼합되어야 하는데 이들이 용제에 고르게 분산되지 않고 일정한 시간이 경과하면 밑으로 가라앉는 침전물이 생기는 것을 의미한다.By the way, the positive electrostatic tomographic electrophotographic photosensitive member composition has a drawback in that stability is not good. Here, the poor liquid stability of the photoconductor composition means that the charge generating material and the charge transporting material should be mixed together, but they do not disperse evenly in the solvent, and after a certain time, a sediment that sinks down is formed.

종래의 정대전 단층형 전자 사진 감광체 조성물은 통상 30일 정도의 액 안정성을 갖는데, 이는 감광체 조성액을 제조한 후 30일이 경과하면 침전물이 생성하여 감광체 조성액을 그대로 사용할 수 없게 되는 것을 의미한다.Conventional positive electrostatic tomographic electrophotographic photoconductor compositions usually have a liquid stability of about 30 days, which means that after 30 days have elapsed from the preparation of the photoconductor composition solution, a precipitate is generated and the photoconductor composition solution cannot be used as it is.

종래의 정대전 단층형 전자 사진 감광체 조성물이 갖는 상기와 같은 문제점을 해결하고자, 본 발명자는 액 안정성이 현저하게 개선된 본 발명의 감광체 조성물 및 이를 제조하는 방법을 개발하기에 이른 것이다.In order to solve the above problems with the conventional positive charge tomography electrophotographic photosensitive composition, the present inventors have come to develop the photosensitive member composition of the present invention and the method for producing the same that the liquid stability is significantly improved.

본 발명의 목적은 액 안정성이 우수한 OPC 드럼용 정대전 단층형 감광체 조성물을 제공하기 위한 것이다.An object of the present invention is to provide a positively charged single layer photosensitive member composition for an OPC drum excellent in liquid stability.

본 발명의 다른 목적은 전하 발생제인 티타늄 프탈로시아닌(TiOPc)을 균일하게 분산시키기 위하여 분산안정제를 부가시킨 정대전 단층형 감광체 조성물을 제공하기 위한 것이다.Another object of the present invention is to provide a positively charged monolayer photoconductor composition in which a dispersion stabilizer is added to uniformly disperse the titanium phthalocyanine (T i OPc), which is a charge generating agent.

본 발명의 또 다른 목적은 액 안정성이 우수한 정대전 단층형 감광체 조성물을 제조하기 위한 방법을 제공하기 위한 것이다.Another object of the present invention is to provide a method for producing a positive charge monolayer photosensitive composition having excellent liquid stability.

본 발명의 상기 및 기타의 목적들은 상세히 설명되는 본 발명에 의하여 모두 달성될 수 있다.The above and other objects of the present invention can be achieved by the present invention described in detail.

발명의 구체예에 대한 상세한 설명Detailed Description of the Invention

정대전 단층형 OPC 드럼은 전하 발생재료와 전하 소송재료를 함께 혼합한 감광체 조성액을 제조하고, 그 감광체 조성액을 알루마이트 도금층 위에 단층으로 코팅하여 제조한다. 정대전 단층형 OPC 드럼은 드럼 내부에 －전하를 걸어주어 드럼 표면에 ＋전하가 형성되도록 한다.The positively charged single-layer OPC drum is prepared by preparing a photoconductor composition liquid in which a charge generating material and a charge lawsuit material are mixed together, and coating the photoconductor composition liquid as a single layer on the alumite plating layer. The positively charged single-layer OPC drums impose negative charges on the drums so that positive charges form on the drum surface.

그런데 정대전 단층형 전자 사진 감광체 조성물은 전하 발생재료와 전하 수송재료가 함께 혼합되기 때문에 액 안정성이 좋지 못한 결점이 있다. 즉 전하 발생재료와 전하 수송재료는 용제에 분산되는데, 시간이 경과함에 따라 이들이 밑으로 가라앉아 침전물이 생기게 된다. 침전물이 생성되면 감광체 조성액을 그대로 사용할 수 없게 된다. 따라서 본 발명에서는 오랜 시간이 경과하여도 침전물이 생기지 않는 액 안정성을 향상시키기 위하여 분산 안정제를 사용하고, 밀링(milling) 공정을 2 단계로 행하는 새로운 제조 방법을 채용한 것이다.However, the positive charge monolayer electrophotographic photoconductor composition has a drawback in that the liquid stability is poor because the charge generating material and the charge transporting material are mixed together. That is, the charge generating material and the charge transporting material are dispersed in the solvent, and as time passes, they sink to the bottom and precipitates are formed. If a precipitate is formed, the photoconductor composition cannot be used as it is. Therefore, in the present invention, in order to improve the stability of the liquid which does not form a precipitate even after a long time, a new production method using a dispersion stabilizer and performing a milling process in two stages is adopted.

본 발명에 따른 OPC 드럼용 정대전 단층형 전자 사진 감광체 조성물은 전하 발생제 0.2∼1 중량%, 상기 전하 발생제를 분산시키기 위한 분산 안정제 0.05∼0.5 중량%, 전자수송물질(electron transport material: "ETM") 2∼5중량%, 홀 수송물질(hole transport material: "HTM") 3∼7중량%, 바인더 수지 6∼15중량%, 및 나머지는 유기용제로 이루어진다.The positively charged single-layer electrophotographic photoconductor composition for an OPC drum according to the present invention comprises 0.2 to 1% by weight of a charge generator, 0.05 to 0.5% by weight of a dispersion stabilizer for dispersing the charge generator, and an electron transport material: ETM ") 2 to 5% by weight, 3 to 7% by weight of a hole transport material (" HTM "), 6 to 15% by weight of a binder resin, and the remainder of the organic solvent.

전하 발생제는 티타늄 프탈로시아닌(TiOPc)이 바람직하고 분산 안정제는 무금속 프탈로시아닌(H2Pc: metal free phthalocyanine)이 바람직하다. 티타늄 프탈로시아닌(TiOPc)은 분자식이 C32H16N8OTi 이고 그 구조식은 하기와 같다.Preferably, the charge generator is titanium phthalocyanine (TiOPc), and the dispersion stabilizer is metal free phthalocyanine (H 2 Pc).
