ABSTRACT:
A cleaning device for an electrophotographic apparatus including a cleaning brush for cleaning unnecessary residual toner particles adhered to an electrostatic latent image retentive member, a cleaning fan for obtaining an air flow to suck the toner particles scraped by the brush and a filter for collecting the sucked toner particles is disclosed. The cleaning device comprises a path of the air flow for sucking the toner particles being made thick at the vicinity of the filter thereby to slow down a speed of the air flow, to easily catch the toner particles by the filter and to drop down the toner particles in front of the filter, and a toner reservoir being provided for collecting the toner particles dropped in front of the filter.
