Abstract

It is commonly known to use a carousel having doctor or wiping blades affixed thereon to remove residual toner particles from the surface of a photoreceptor as illustrated, for example, in laid-open Japanese Patent No. 61-122679 (A) (Appl. No. 59-243203) to Fuji Xerox Co., Ltd. Also, it is known to use a vacuum source in conjunction with a brush-type cleaner to improve the removal of residual toner. The present disclosure is directed toward a combination of the known cleaning methods and proposes the use of a carousel-type blade cleaner in conjunction with a vacuum source.

The present disclosure is directed toward a combination of the known cleaning methods and proposes the use of a carousel-type blade cleaner in conjunction with a vacuum source.

As shown in the figure, blade assembly 12 is comprised of a hollow cylindrical core, 14, which is closed on one end, and a plurality of blades 16 extending radially from the circumference of the core. The blades are affixed to the core in a direction parallel to the surface of photoreceptor drum 20 so as to act either as wiping blades or as doctor (scraping) blades, both of which would generally remove residual toner from the photoreceptor surface. Moreover, the core contains a plurality of blades which may be indexed periodically to present a different blade edge for the cleaning o eration. Also includ...
