摘要： There is provided an image forming device capable of preventing smudges on the background of an image due to excess toner replenishment caused by a failure in stirring developer and toner enough to charge the toner or scattering of replenished toner without being charged. A toner conveying member for conveying replenished toner from a toner replenishing portion through a toner replenishing port to a developer stirring and conveying member is constructed by a screw member unitarily formed with the developer stirring and conveying member. The screw member has a spiral conveying fin capable of conveying the replenished toner at relatively high speed. The replenished toner is delivered to a toner replenishing portion provided in the upstream of a developer receiving portion of the screw member.

摘要： The clean surfaces of rollers in contact with photoconductive element of an image forming apparatus are cleaned of toner and other contaminants by increasing pressure between the contact surfaces of the roller and the photoconductive element during non-sensitive phases of operation, so that toner and other contaminants are transferred from the rollers to the photoconductive element. Alternatively, the rotational speed of the rollers are decreased, increased or reversed during non-sensitive phases of operation to effect transfer of toner and other contaminants to the photoconductive element for removal by the development station and/or development station. The system and cleaning method, which is particularly useful for charging, transfer and discharging rollers, are applicable to image forming apparatus wherein accumulation of toner and other contaminants decreases the quality of reproduction, require troublesome maintenance, decrease the life of the rollers requiring replacement, and prevents a compact image forming apparatus.
