    摘要: In an electrostatic both-side printing system, a first image forming unit is provided upstream of an image printing medium when viewed in the transporting direction of the image printing medium, and a second image forming unit is provided downstream of the image printing medium. A medium transporting path for transporting the image printing medium is formed between the first and the second image forming units. A first transferring unit, located facing the first image forming unit with the medium transporting path intervening therebetween, for applying no charge onto the rear side of the image printing medium, which does not face the first image forming unit. A second transferring unit being located facing the second image forming unit with the image printing medium with the medium transporting path intervening therebetween, in a state that the second transferring unit is apart from a first toner image formed on the image printing medium by the first image forming unit. In the both-side printing system thus constructed, the first and the second image forming units, and the first and the second transferring units cooperate to form first and second toner images on both sides of the image printing medium, the first and the second toner images being opposite in polarity.

    摘要: Apparatus for monitoring the concentration of toner in a mass of developer mix including the toner and carrier particles, having a sampling cylinder inside which the developer mix flows. An accumulating cylinder is disposed over the sampling cylinder. At the upper end part of the accumulating cylinder, a guide plate is disposed by which the developer mix is supplied to the accumulating cylinder. At the lower end part of the accumulating cylinder, a developer mix supplying roll is disposed by which the developer mix at a fixed flow rate is supplied to the upper end opening of the sampling cylinder. On the other hand, at the lower end opening of the sampling cylinder, there is disposed a magnet roll by which the developer mix at a fixed flow rate is discharged from inside the sampling cylinder. The flow rate of the developer mix to be supplied to the sampling cylinder is set to be greater than the flow rate of the developer mix to be discharged, so that part of the developer mix supplied towards the sampling cylinder overflows from the upper edge of the sampling cylinder. Therefore, the developer mix inside the sampling cylinder flows in a stable state. A detecting coil is disposed on the outer periphery of the sampling cylinder, and detects the toner concentration of the developer mix in the form of an inductance.

    摘要: A cleaning device for a dry electrophotographic device includes a cleaning brush brought into resilient contact with an object to be cleaned such as a photosensitive drum. A cleaning roll rotates while constantly being brought into contact with the cleaning brush and a cleaning blade is pressed against the cleaning roll to clean the cleaning roll. A rotation direction switching mechanism switches the rotation direction of the cleaning brush such that the rotation direction of the cleaning brush when cleaning the object, for example, during the formation of an image, is different from that when the brush is not cleaning the object.

    摘要: Disclosed is a second toner developing apparatus for use in a two color electro-photographic recording apparatus in which a photosensitive drum is uniformly charged, subject to a first exposure, developed with a first toner, subject to a second exposure, and then developed with a second toner. The second developing apparatus is provided with a rotary sleeve for performing magnetic brush development and a fixed magnet disposed within the rotary sleeve. The fixed magnet includes a plurality of magnetic poles of the same polarity provided close to each other, so as to temporarily separate the second developer from the surface of the rotary sleeve at the position of these same polarity magnetic poles. An electrostatic attraction electrode attracts the first toner mixed in the thus separated second developer to thereby remove the first toner from the second developer.
