Abstract

PURPOSE:To perform efficient cleaning at a relatively low speed by providing electrodes, applied with a voltage of the opposite polarity to charged toner, in a flocked sleeve and to a metallic roller for recovery. CONSTITUTION:In a flocked sleeve 2 for cleaning, fixed electrodes 3 are provided at fine intervals, and are applied with a voltage of the opposite polarity to charged nonmagnetic toner 5. Therefore, residual toner 5 on a recording medium 1 is attracted to the sleeve 2 by Coulomb force at the opposite part to the electrodes 3, carried through the rotation of the sleeve, and attracted to and passed to a metallic roller 4, applied with a voltage of the opposite polarity, where the influence of the electrodes 3 is eliminated to be scraped off by a blade 6, thereby colecting it in a container 7. The toner is passed by utilizing the Coulomb force, so efficient cleaning is carried out.

Conventionally, in the case of non-magnetic toner in this type of cleaning device, a fur brush is used to scrape off the remaining toner toward the recording medium, and the dropped toner is carried on the airflow inside the device. The toner is attracted to a metal roller to which a voltage is applied (by electric force), and is scraped off and collected by a toner removing blade attached to the metal roller. However, with such a leaning device, it is necessary to rotate the fur book at high speed to ensure airflow inside the device, which causes problems such as brush wear and hair removal, and also causes 74 luming on the surface of the recording medium. This has various drawbacks, such as deterioration of the recording medium and an increase in the size of the entire device.
