    摘要： Copying apparatus is provided in which outline copying for only a designated area of an original image can be easily selected. An area for the outline copying can be designated and images inside and outside the designated area can be copied in different colors. The arrangement includes a plurality of keys for designating an area of an original image to be copied and a scorotron charger for causing a potential in areas other than the outline portions of an electrostatic latent image, formed on a photoreceptor drum, to be substantially equal to a potential in an area containing the image. An eraser unit is provided for erasing the charge in an area where development is not required and a developing device develops the electrostatic latent image. A transfer charger is provided for transferring the image developed by the developing device onto copying paper. When an area of the original images designated and an outline image forming mode is selected by the operator of the machine, two copy operations are performed to composite an outlined image formed inside or outside the designated area and a normal image formed in the area which does not include the outline image so that a composite image is copied onto the copy paper.

    摘要： An electrophotographic image forming apparatus employing a two-component developer including toner and carrier comprises: a developing unit containing the developer; a toner concentration sensor provided on the developing unit for detecting the concentration of the toner included in the developing unit; a comparing apparatus for comparing a value detected by the toner concentration sensor with a prescribed concentration reference value; a supplying apparatus for supplying toner to the developing unit; a controlling apparatus for controlling toner supply by the supplying apparatus based on the result of comparison by the comparing apparatus; and a detecting apparatus for detecting whether or not a detachable member whose attachment influences the detection of the toner concentration sensor is attached near the developing unit. The controlling apparatus changes the amount of toner supply by the supplying apparatus based on detected value from the toner concentration sensor in response to the detection output from the detecting apparatus.

    摘要： An image forming apparatus wherein the copying operation is performed not only in an automatic density specifying mode but also in a manual density specifying mode according to select by an operator. When the ratio of the frequency of select of the manual density specifying mode to the frequency of select of the automatic density specifying mode has exceeded a predetermined value, the image forming apparatus is adapted to execute an image adjustment process by detecting the state of components, for example, charge wires for the purpose of adjusting the density of copy images formed in the automatic density specifying mode.

    摘要： A copying machine for carrying out simplex, duplex and composite copying operations, wherein a sheet is re-fed to an image forming section in a duplex or composite copying mode. The machine includes two sheet discharge sections, a size evaluating device for judging the size of a sheet in the course of sheet transport, and a reversible roller pair disposed adjacent one of the discharge sections. When the sheet has a size fit for re-feeding for a second image formation in the duplex copying mode, the reversible roller pair is controlled to re-feed the sheet in a switchback fashion to the image forming section. When the sheet is too small, the reversible roller pair discharges the sheet through to the discharge section.
