摘要： An electrophotographic image forming apparatus including a toner circulating mechanism for recovering a residual toner scraped from a photosensitive drum to a developing device. The developing device includes a housing for defining a toner chamber, a developing roller rotatably mounted in the housing, an agitator rotatably mounted in the housing and provided in the toner chamber, and a partition member mounted to the housing to define a carrier chamber between the partition member and the developing roller. The toner circulating mechanism directly returns the residual toner scraped from the photosensitive drum to the toner chamber in the developing device. The toner chamber may contain a foreign matter removing device. The partition member may have various shapes.

摘要： An object of the present invention is to provide a feeder, image-forming device, and remaining amount detecting method that allows a user to simply and effectively determine upon issuing a print command whether the print command will be executed completely without a loss of paper. The inventive feeder for feeding a recordable medium to a processor part that performs a process comprises: a sheet placement part that can accommodate a plurality of the recordable media in a stack of layered sheets, and rotate and shift to a suitable position for feeding the recordable media to the processor part; and a shift amount indicator part that is configured to rotate in a direction of rotation of the sheet placement part as the sheet placement part rotates, so as to enable a shift amount of the sheet placement part corresponding to a remaining amount of the recordable media to be electrically transmitted to an external device.

摘要： An electrophotographic image forming apparatus includes an electrostatic latent image carrying body, an electrifying unit for electrifying the image carrying body, a light irradiating unit to form an electrostatic latent image in accordance to image information, a developing unit for discharging toner to the image carrying body to develop the latent image, a transfer unit for transferring the toner image to a recording sheet, and a cleaner for removing residual toner on the image carrying body. The toner removed from the image carrying body is recirculated to the developer receiving box. An additional toner image is formed on a position other than a first position where the electrostatic latent image is formed in accordance with the image information. The toner is removed by the cleaner without being transferred to the recording sheet and recirculated from the image carrying body to the developer receiving box.
