Embodiment Construction

[0052] Hereinafter, an embodiment in which the present invention is applied to a printer (hereinafter referred to as a printer) as an image forming apparatus will be described.

[0053] figure 2 It is a schematic configuration diagram showing main parts of the printer of this embodiment. The printer performs single-color reproduction, and forms an image based on image data read by an image reading unit not shown in the figure.

[0054] Such as figure 2 As shown, the printer has a drum-shaped photoreceptor 3 as an image carrier. Although the photoreceptor in the figure is in the shape of a drum, it may also be in the shape of a sheet or an endless belt.

[0055] Around the photoreceptor 3, a charging device is arranged, a developing device 5 for turning the latent image into a toner image, a transfer device 7 for transferring the toner image to a transfer paper as a transfer body, and a transfer device 7 for transferring the toner image to a transfer paper. The separation...

Abstract

The invention relates to a cleaning blade and an image forming apparatus, a process cartridge, and an image forming method using the same. A cleaning blade for removing fine particles from a cleaning target by contact with the cleaning target is provided. The cleaning blade includes an elastic blade A leading edge of the elastic blade includes a friction coefficient of 0.5 or less. The cleaning blade also includes a surface layer that covers the leading edge of the elastic blade. A thickness of the surface layer is between 1 to 50 mu m at a position 50 mu m away from the leading edge, and a hardness of the surface layer is greater hardness than the elastic blade.

Description

technical field [0001] The present invention relates to a cleaning blade used in image forming devices such as printers, facsimiles, and copiers, an image forming device having the cleaning blade, a process cartridge, and an image forming method. Background technique [0002] In the past, in the image forming apparatus of electrophotography type, after the toner on the image carrier such as the photoreceptor as the object to be cleaned is transferred to the transfer paper and the transfer body, adhering to the surface Unnecessary remaining toner, which is removed with a cleaning device. [0003] It is well known that the cleaning parts in such cleaning devices generally use rectangular cleaning blades from the viewpoint of simple structure and excellent cleaning performance. Such a cleaning blade is made of a rectangular elastic body such as polyurethane. The bottom end of the cleaning blade is supported by the supporting member, and the transition portion at the front end...
