发明名称 Electrophotographic recording apparatus having improved residual toner cleaning function
摘要 In an electrophotograpic recording apparatus, a charge supply unit and a light erasing unit are disposed in the stated order when viewed in the direction in which a photoreceptor rotates, at a location between a transfer unit and a bias cleaning unit, and light from the light erasing unit is projected onto a photoreceptor surface area except the charge supplied area. A developing apparatus of the type in which a cleaner section for removing and collecting residual toner on a photoreceptor is coupled through a toner transport pipe with a toner hopper of a developing unit, wherein a meshed foreign material collector, which may be vibrated, is disposed at a location in a residual toner collecting path ranging from the cleaner section, the toner transport pipe, and the toner hopper.
