摘要： A developing apparatus includes a developing roller which conveys developer on the surface thereof by the rotation in a predetermined direction. The developer conveyed thereon to develop a latent image formed on an image-holding device. A supply roller rotates keeping contact with the developing roller and by the rotation of which the developer is supplied to the developing roller. A regulating member regulates the amount of the developer to be conveyed on the surface of the developing roller. The supply roller is so disposed that the axis thereof is positioned lower than that of the developing roller while the top thereof is also positioned lower than that of the developing roller.

摘要： Conveying devices, operation of which is stopped during printing, are provided upstream and downstream, as seen in a direction of conveying of a paper, of a platen arranged to face a printing head. The platen is provided with an electrostatic attraction member electrostatically the paper by the application of a voltage. A first control applies the voltage to the member during printing until a leading end of the paper arrives at the downstream conveying device. A second control applied the voltage to the member during printing after conveyance of a trailing end of the paper by the upstream conveying device is completed. Thereby, lifting of the end portions of the paper away from the platen is prevented, thus avoiding unprintable margins at such end portions of the paper.

摘要： A document size detecting device with the arm which folds by interlocking with the reciprocating motion of the optical system of the image forming apparatus and extends and contracts by interlocking with the reciprocating motion of the optical system. The optical sensor for detection of the document size is installed at a prescribed position of the arm and the feeder line for the light source is held. Therefore, the special mechanism for holding the feeder line is not necessary and it is possible to achieve simplified construction of the image forming apparatus. Also, because the feeder line is caused to curve along the outside of the arm at the rotating section thereof, it is possible to provide a large radius of the bent portion of the feeder line, there will be no considerably concentrated stress which is locally applied to the feeder line, therefore the life of the feeder line can be extended.

摘要： In a cap mode where a cap member covers a nozzle surface, a controller controls a second movement mechanism so that the cap member is disposed opposite to the nozzle surface. In an ejection recovery mode where ink is ejected from a plurality of nozzles and the ink adhered to the nozzle surface is wiped off by a wiping member, the controller controls a first movement mechanism and the second movement mechanism so that the nozzle surface, a wiping tray and the cap member are arranged downward in this order.
