Embodiment 1

[0173] After washing the surface of the roller with dirt attached thereto with water and air-drying it, the roller was irradiated with ultraviolet rays (wavelength: 184.9 nm and 253.7 nm) at intervals of 90° along its circumferential direction by an ultraviolet irradiation lamp 5 cm apart from the roller 5 minute. The roll was rotated 4 times at 90° to irradiate its entire outer surface (360°) in one pass. The surface of the developing roller was irradiated with ultraviolet rays at intervals of 90° for 5 minutes. The total irradiation time period is then 20 minutes.

Embodiment 2

[0175] After blowing air on the surface of the developing roller on which the dirt was attached, the surface was irradiated with ultraviolet rays for the first time. The surface of the roller is then washed with water. After the surface of the roll is air-dried, its surface is irradiated with ultraviolet rays for the second time.

[0176] The conditions of the first irradiation and the second irradiation of ultraviolet rays and the conditions of washing the surface of the roller with water were similar to those used in Example 1.

Embodiment 3

[0178] After air was blown on the surface of the roller with dirt attached thereto, the surface thereof was irradiated with ultraviolet rays. After washing the surface of the roller with water, it is air-dried.

[0179] The irradiation conditions of ultraviolet rays and the conditions of washing the surface of the roller with water were similar to those used in Example 1.

[0180] ·Reference example

[0181] A new rubber roller on which no dirt was attached was used.

Abstract

The present invention provides a method for recycling a spent image-forming member mounted inside an image-forming apparatus to reuse the image-forming member. In the method, the image-forming member is made of an elastomer before the image-forming member is recycled; and when a recycling work is performed, a surface of the image-forming member is not abraded, but irradiated with ultraviolet rays or ozone at least once to decompose or / and deteriorate a deposit which has attached to the surface thereof in a use thereof so that the deposit is removed from the surface thereof.

Description

[0001] This application claims priority from Patent Application No. 2007-144888 filed in Japan on May 31, 2007, the entire contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a method for recycling an imaging component, and more particularly to a method for recycling an imaging component used in an imaging device in the form of a cartridge, and by reinstalling the imaging component in the imaging device to reuse the imaging unit. Background technique [0003] Image forming apparatuses typified by laser beam printers and inkjet printers are widely used not only for business use but also for home use. A large number of imaging devices have been put on the market. In the imaging device, the discarded part is replaced as a built-in replacement part, ie as a cartridge, as a whole. [0004] Many parts such as a rubber roller formed of an elastomer composition (hereinafter simply referred to as "elastomeric parts") are...
