ABSTRACT:
A recovered toner classifier includes a rotatable cylindrical-shaped filter and a fur brush having a brush spirally provided on an outer peripheral surface of a rotation shaft. A non-brush region is continuously formed from the inlet of the filter for the recovered toner through the outlet of the filter for discharging the disposal toner along the axis line of the rotation shaft. The fur brush integrally rotates with the rotation shaft with a tip portion of the brush is in press-contact with an inner peripheral surface of the filter. A screw conveyer having a screw on a portion of the rotation shaft on a side of the inlet of the filter for the recovered toner is provided to convey the recovered toner to the inlet of the filter for the recovered toner.
