摘要

A cleaning device comprising a housing disposed above a photoconductor drum and having an opening portion open downward toward the circumferential surface of the photoconductor drum, a cleaning blade disposed in the housing so as to be located in the opening portion downstream in the direction of rotation of the photoconductor drum, and a cleaning roller disposed in the housing so as to be located in the opening portion upstream from the cleaning blade in the direction of rotation of the photoconductor drum; and an image forming apparatus equipped with the cleaning device. In the housing of the cleaning device, a spiral roller for letting out a toner recovered into the housing is disposed above the cleaning blade. A partition wall is disposed between the cleaning blade and the spiral roller, and a toner movement space for moving the toner recovered into the housing is formed between the front end of the partition wall and the circumferential surface of the cleaning roller.
