Abstract

PURPOSE: To improve cleaning efficiency and the life of a fur brush by beforehand erasing the charge of the excess toner, etc. removed by the fur brush by AC corona wind and insulating a housing for brush from ground potential.
CONSTITUTION: The charge of the excess toners 4 removed by a photoreceptor 1 and a fur brush 2 is erased by an AC corona wind generator 20 formed by an AC corona destaticizer 8, a fan 13, etc. The toners 4... of the erased electrical absorbing power are sucked into the suction port 10 of a housing 3 together with the air from the opening 12 of the housing 3 of the fur brush 2 and the remaining toners 4... which could not have been cleaned are easily electrostatically picked up on the bursh 2 from the photoreceptor 1 and are removed without accumulating. In addition, the housing 3 is held insulated from ground potential, thus even if there is some residual charge in the toners 4..., the electrostatic pickup and accumulation on the brush 2 are prevented, whereby the highly efficient cleaning may be done and the extention of the life of the fur brush may be achieved.
