Embodiment Construction

[0030] First, an example of an electrophotographic apparatus embodying the present invention will be described.

[0031] exist Figure 10 In , the structure of the image forming section of the electrophotographic apparatus of this example is shown.

[0032] The illustrated electrophotographic apparatus is generally of a so-called tandem type intermediate transfer type, and includes, as typical functional sections, the following: a plurality of image forming units 1Y, 1M, 1C, and 1K in which electrophotographic methods are used to forming toner images of various color components; a primary transfer section 10 that sequentially transfers (primary transfer) the toner images of various color components formed by the respective image forming units 1Y, 1M, 1C, and 1K to an intermediate transfer on the printing belt 15; a secondary transfer section 20 that collectively transfers (secondary transfers) the superimposed toner images transferred onto the intermediate transfer belt 15 on...

Abstract

The present invention provides a cleaning device and an electrophotographic device. The cleaning device includes: a brush roller that removes residual toner remaining on a surface of a toner image carrier provided in an electrophotographic device; and a pressure detector that contacts the surface of the brush roller with a predetermined load and will detect The pressure value is output to a judgment unit provided in the electrophotographic device to judge the adhesion state of the toner on the brush roller.

Description

technical field [0001] The present invention relates to a cleaning device for removing residual toner remaining on the surface of a toner image carrier provided in an electrophotographic device, and an electrophotographic device including the cleaning device. Background technique [0002] Electrophotographic devices are, for example, devices such as copiers, facsimile machines, printers, and multifunction machines combining these functions by transferring a toner image carried on a carrier such as a photosensitive drum to a recording medium such as paper. Come up to form an image. [0003] Such an electrophotographic apparatus includes a cleaning device that removes residual toner remaining on the surface of the toner image carrier, and the cleaning device cleans the surface of the carrier to which the toner image is transferred. [0004] JP-A-2006-106017 (Patent Document 1) discloses an invention in which a cleaning blade made of an elastic An index value based on a norma...
