ABSTRACT:
A printer comprises a removable process unit which includes a photoconductive drum and an image forming section for forming an image on the drum. The process unit is provided with a removing member for removing dust from a transfer medium adhering to an aligning roller and a dust storage section for storing the dust removed by the removing member. The storage capacity of the dust storage section is larger than a capacity equivalent to the volume of the dust removed as the transfer medium corresponding in quantity to the service life of the process unit is processed.
