PURPOSE: To continue an excellent cleaning performance for many hours, and also, to scarcely damage the body to be cleaned by constituting the brush so that the raised hair length is raised hair A < raised hair B, the raised hair concerned A consists of a conductive fiber containing a conductive component, and the raised hair concerned B consists of an insulating fiber whose raised hair tip has a sharp shape.

CONSTITUTION: This brush 1 is constituted by mixing many raised hair A 2 and raised hair B 3 and allowing them to stand close together, and the raised hair A consists of a conductive fiber containing a conductive component. Also, the tip part of the raised hair B has a sharp shape. Moreover, the raised hair length consists of combination of a fact of the raised hair A < the raised hair B. In such a way, frictional electrification of a residual untransferred toner, a photosensitive body and the brush itself is prevented, and the residual untransferred toner can be scraped off quickly and efficiently from the photosensitive body to the brush. Also, the brush has a strong scraping action and a satisfactory cleaning performance. Moreover, the raised hair A scarcely comes into contact directly with a body to be cleaned, and cutting and permanent strain of the fiber can be decreased remarkably, comparing with a conventional brush.
