Embodiment 1

[0007] Example 1: Polycarbonate PCZ-300 is dissolved in 1,2-dichloroethane to prepare a film-forming agent solution with a mass concentration of 10%; Y-type oxytitanium phthalocyanine, diphenoquinone and forming The film solution is mixed in a mass ratio of 1:40:4000, dispersed by a ball mill to prepare a coating liquid. Coat the coating liquid on the aluminum drum base with pre-coated insulating layer, and dry it at 80°C for 3 hours. The thickness of the single-layer photoconductive composite layer of the fabricated device is 22 μm. The photoelectric performance parameters are shown in Table 1. The resulting device is sensitive to near-infrared light and can be applied to positive charging laser printers.

Embodiment 2

[0008] Embodiment 2: Polycarbonate PCZ-300 is dissolved in 1,2-dichloroethane to prepare a film-forming agent solution with a mass concentration of 10%; Y-type oxytitanium phthalocyanine, diphenoquinone and forming The film solution is mixed in a mass ratio of 1:60:4000, dispersed by a ball mill to prepare a coating solution. Coat this coating solution on the aluminum drum base with pre-coated insulating layer, and dry it at 60-90°C for 1-3 hours. The photoelectric performance was measured with a PDT-200 organic photoconductive drum analyzer, and the photoelectric performance parameters are shown in Table 1. The resulting device is sensitive to near-infrared light and can be applied to positive charging laser printers.

Embodiment 3

[0009] Example 3: Polycarbonate PCZ-300 is dissolved in 1,2-dichloroethane to prepare a film-forming agent solution with a mass concentration of 10%; Y-type oxytitanium phthalocyanine, diphenoquinone and forming The film solution is mixed in a mass ratio of 1:80:4000, dispersed by a ball mill to prepare a coating solution. Coat this coating solution on the aluminum drum base with pre-coated insulating layer, and dry it at 60-90°C for 1-3 hours. The photoelectric performance was measured with a PDT-200 organic photoconductive drum analyzer, and the photoelectric performance parameters are shown in Table 1. The resulting device is sensitive to near-infrared light and can be applied to positive charging laser printers.

Abstract

A method for preparing organic photoconductor drum with positive charge characteristic includes dissolving Merlon in organic solvent to prepare film forming agent solution, mixing said agent solution and metal phthalocyanine as well as biphenyl quinine together as mass ratio of 1: 40: 4000-1:100 :8000, scattering mixed material to be coat liquid, coating said coat liquid on aluminium drum base being oxidized by anode, drying coated alminium drum to form organic photoconductor drum with positive charging characteristic.

Description

(1) Technical field [0001] The invention relates to a method for manufacturing a single-layer positively chargeable organic photoconductive drum. (two), background technology [0002] Since Carlson invented dry electrophotography using anthracene as a photoconductive material in the 1930s [US Patent 2,221,776 (1940)], photoconductive materials have been greatly developed as information recording materials. With the rapid development of today's information technology, office automation has spread to almost every field of social life. As the core component of laser printing and electrostatic copiers, organic photoconductive drums are in increasing market demand. Therefore, the organic photoconductive drum and its organic photoconductive materials have attracted more and more attention. The organic photoconductive drum (OPC), which is the core component of laser printing and electrostatic copiers, is simply a layer of photoconductive material coated on a conductive aluminum ba...
