Problems solved by technology

However, since this method causes materials other than toner to adhere to the charging roller, the charging performance is degraded, and the rotation of the charging roller is unstable, which easily causes problems of jumpy images (lines in the printing direction)

Embodiment Construction

[0020] Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

[0021] FIG. 1 is a schematic cross-sectional view of a printer 1 which is one example of an image forming apparatus according to an embodiment of the present invention. In addition, the present invention is not limited to printers, but can also be applied to other image forming apparatuses such as copiers, facsimile machines, and multifunction machines.

[0022] The printer 1 is an image forming apparatus that forms an image on paper based on image data sent from a terminal or the like while paper is being conveyed along a conveyance path L. As shown in FIG. The printer 1 has, inside a box-shaped main body 2, an image forming unit 4 for transferring a toner image to paper after forming a toner image on the surface of a photosensitive drum 3; The paper is supplied to the image forming unit 4; and the fixing unit 6 fixes the toner image on the p...

Abstract

An image forming apparatus is provided with a rotary image bearing member; a charging roller for charging the outer circumferential surface of the image bearing member by rotating in contact with the image bearing member; a brush roller for cleaning adhered matters on the outer circumferential surface of the charging roller by being held in contact with the charging roller due to its own weight and rotating; a driving mechanism for drivingly rotating the brush roller to have a linear velocity difference to the charging roller; and a moving mechanism for reciprocating the brush roller along the longitudinal direction thereof. Thus the image forming apparatus is designed to prolong the life of the cleaning performance of a brush roller and capable of suppressing the formation of jitter images.

Description

technical field [0001] The present invention relates to an image forming apparatus such as a printer, a copier, a facsimile, and a multifunction peripheral having these functions. Background technique [0002] At present, a known image forming device includes: a charging roller that rotates synchronously with the photosensitive drum to charge the surface of the photosensitive drum; A brush roller for cleaning agents, etc., wherein the brush roller abuts against the charging roller due to its own weight, and is driven to rotate by the charging roller. (For example, refer to JP-A-2005-4065). [0003] However, in such an image forming apparatus, since the brush roller is driven to rotate by the charging roller, the cleaning power is weak, and the service life of hundreds of thousands of sheets cannot be achieved. Therefore, in order to enhance the cleaning power, it is considered to increase the weight of the brush roller. However, in this method, since materials other than ...
