Abstract

(57) [Summary] [Structure] OPC (organic photoconductor) cleaner nozzle 2, charging section 6, exposure section 7, developing section 8, transfer section 9, erase section 1
0 is arranged around the OPC drum 1, the toner filter 3, the suction device 4, and the pipe 5,
The toner filter 3 removes unnecessary toner on the surface of the OPC drum 1 without bringing the PC cleaner nozzle 2 into contact with the OPC drum 1.
Through pipe 5, and removed by suction device 4. [Effect] With the above configuration, the OPC drum is not worn or damaged, so that the printing quality of the OPC drum can be improved and the life of the OPC drum can be extended.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an electrophotographic apparatus such as a copying machine or a printer, and more particularly to a cleaner for removing unnecessary toner.

[0002]

[Prior art]

 A conventional organic photoconductor (hereinafter referred to as OPC) cleaner unit removes unnecessary toner on the surface of the OPC drum by pressing a plate-shaped blade against the surface of the OPC drum.

Besides, unnecessary toner on the surface of the OPC drum is removed by rubbing the surface of the OPC drum while rotating the brush.

[0004]

[Problems to be solved by the device]

 In the conventional OPC cleaner unit described above, a plate-shaped blade is pressed against the surface of the OPC drum, or the brush is rotated to rub the surface of the OPC drum, so that the surface of the OPC drum is rubbed and the OPC is worn. However, it has the drawback of being scratched.

An object of the present invention is to eliminate the above-mentioned drawbacks by allowing unnecessary toner on the surface of the OPC drum to pass through a pipe through a toner filter and to be removed by a suction device without contacting the OPC cleaner nozzle with the OPC drum. The object is to provide an OPC cleaner unit in which the OPC drum is not worn or scratched by improving the printing quality of the OPC drum and extending the life of the OPC drum.

[0006]

[Means for Solving the Problems]

 The OPC cleaner unit of the present invention comprises an OPC cleaner nozzle having a rectangular opening and arranged in parallel and close to the cylindrical direction of the OPC drum, a toner filter for removing toner sucked from the OPC cleaner nozzle, and an OPC drum. It has a suction device for sucking the toner on the surface from the OPC cleaner nozzle and a pipe for carrying the toner sucked by the suction device.

[0007]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic view of an OPC cleaner unit according to an embodiment of the present invention.

Around the OPC drum 1 shown in FIG. 1, an OPC cleaner nozzle 2, a charging unit 6, an exposing unit 7, a developing unit 8, a transferring unit 9, and an erasing unit 10 are arranged.

The OPC cleaner nozzle 2 is connected to the toner filter 3 by the pipe 5, and the toner filter 3 is connected to the suction device 4 by the pipe 5.

A toner image is formed on the OPC drum 1 that has passed through the charging unit 6, the exposing unit 7, and the developing unit 8 by the electrophotographic process, and the toner image is transferred onto the sheet by the transfer unit 9.

The unnecessary toner remaining on the OPC drum 1 is sucked at the OPC cleaner nozzle 2 by the suction force generated by the suction device 4, passes through the pipe 5, and is collected and removed by the filter 3.

Next, the erase section 10 erases unnecessary electrostatic charges on the OPC drum 1, and the cycle of the electrophotographic process is repeated again.

[0014]

[Effect of device]

 As described above, the OPC cleaner unit of the present invention removes unnecessary toner on the surface of the OPC drum without contacting the OPC cleaner with the OPC drum, so that the OPC drum is not worn or damaged. , Has the effect of improving the print quality of the OPC drum and extending the life of the OPC drum.
