摘要： An image forming apparatus which is capable of adjusting toner density in response to variations of humidity. The image forming apparatus includes a toner density detector that detects the density of toner inside an image developer, a humidity detector that detects toner humidity inside the image forming apparatus, and a controller that controls a toner supplier on the basis of the toner density detected by the toner density detector and that adjusts the toner density in accordance with variations of humidity detected by the humidity detector. The humidity detector is located at a position where the humidity detector can detect humidity of air around the image developer and where the humidity detector is minimally affected by heated air.

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.

A memory device stores resultant value of the toner density detected by the toner-density detecting device during image forming operations. The toner-density detecting device detects the toner density in a warm-up operation before starting the image forming operation by the image forming apparatus. The toner-density control device changes an amount of the toner supply which is supplied by the toner supplying device after starting the image forming operation according to a result of a comparison of the detected toner density in the warm-up operation with the detected result stored in the memory device. The toner-density control device changes an amount of the toner supply which is supplied by the toner supplying device after starting the image forming operation according to the resultant value of comparison of a result of a detection.

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.
