摘要： An image forming apparatus includes a developer unit to store two-component developer which includes toner and carrier and develop an electrostatic latent image formed on the image carrier, a toner concentration detector to detect toner concentration in the developer unit, a toner supply unit to supply toner to the developer unit, and a controller to control toner supply amount by controlling the toner supply unit by comparing an output value of the toner concentration detector with a reference value stored in a memory and correcting difference between output values of the toner concentration detector at two or more process linear velocities in accordance with the toner concentration in the developer unit. A compensation amount for correcting difference between output values of the toner concentration detector that differ depending on the process linear velocity is adjustable in accordance with the toner concentration in the development unit.

摘要： A lens mounting plate to which a projection lens unit is fixed is brought into contact with a sliding base. The lens mounting plate is pressed against the sliding base by the urging of a coiled spring. The pressing force is set such that the position of the projection lens unit can be held and shifted. A cover is provided with a pipe-shaped projection so as to surround the projection lens unit with a clearance corresponding to the shifting width of the projection lens unit between the pipe-shaped projection and the projection lens unit. A user shifts the position of the projection lens unit with his or her fingers laid on the pipe-shaped projection and the projection lens unit.

摘要： An image forming apparatus of the present invention includes an image carrier on which a developer is to be deposited by an electrophotographic system. A controller controls the amount of the developer to deposit on the image carrier by varying a potential for development. A reflection type sensor for sensing the amount of the developer deposited on the image carrier is made up of a light source and a light-sensitive device for. An adjusting device adjusts a set value set in the controller for controlling the amount of the developer to a target value. The sensor is of a diffuse reflection system and has a correcting function. The adjusting device causes the sensor to sense the amount of the developer deposited on a test patch, which is formed on the basis of a preselected set value, and then calculates an adjustment value of the set value on the basis of the amount sensed by the sensor and the target value.

摘要： In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, a CCD sensor detects an unremoved image formed by a stamp, additional writing, etc. and left on the transfer paper sheet after toner separating processing is performed with respect to the transfer paper sheet by a liquid-providing toner-separating unit. A discriminating mark such as a punch, a mark o, etc. is additionally provided to the transfer paper sheet having the detected unremoved image by a discriminating mark providing unit. The transfer paper sheet having the discriminating mark is automatically sorted by a sorting unit and is discharged onto a paper discharging tray. The toner removing apparatus may have an unrecognizing device for blotting the unremoved image such as a seal print, a signature, etc. on the transfer paper sheet. The unrecognizing device may coat the unremoved image with ink having the same color as the unremoved image, or may punch the unremoved image. Thus, it is possible to prevent the transfer paper sheet having the unremoved image from being used or thrown away in error and prevent the unremoved image from being abused in advance.

摘要： In a method and an apparatus for removing an image forming substance such as toner from an image holding member such as a sheet of transfer paper, an unstabilizing agent is provided to the image holding member. An attaching state between the image forming substance and the image holding member stably attaching the image forming substance on a surface thereof is changed to an unstable state by the unstabilizing agent. The image forming substance is separated and removed from the image holding member by making a separating member come in close contact with the image forming substance on the image holding member having the provided unstabilizing agent. A processing situation mark showing a processing situation of removal of the image forming substance is formed in the image holding member. The processing situation mark can be removed from the image holding member by the image forming substance removing processing.

摘要： A predetermined processing liquid is supplied by a liquid supplying unit to a sheet of transfer paper having a surface on which toner is stably attached. An adhesive state of the toner on the transfer paper sheet is changed to an unstable adhesive state. The processing liquid is constructed by water, aqueous solutions of a surfactant, a water-soluble polymer, etc. The transfer paper sheet including the processing liquid is fed to a toner separating unit. While the toner is heated and pressurized in the toner separating unit, the toner is attached to a separating roller having a surface on which the softened toner is easily attached. The toner separating unit then separates only the transfer paper sheet from the surface of the separating roller by a separating claw. The processing liquid is removed from the transfer paper sheet by heating the transfer paper sheet, etc. using a drying unit such that the transfer paper sheet can be reused for a copying machine, etc. Thereafter, the transfer paper sheet is discharged onto a paper discharging tray. Accordingly, it is possible to provide a method and an apparatus for regenerating and reusing the transfer paper sheet by removing the toner therefrom without damaging paper fibers.
