Abstract
PURPOSE: To prevent the change of developed images with time by separating toner once from sleeve surface by a toner isolating member and conveying the toner then supplying the same again to the sleeve surface by gravity fall.
CONSTITUTION: In the conveying method of one-component magnetic toner of holding and conveying the toner 3 supplied from a containing vessel 5 by the developing roll consisting of a non-magnetic conductive cylindrical sleev 1 and the magnetic roll provided therein, a toner isolating member 10 is provided in proximity to the sleeve 1 surface and the toner 3 is once separated from the sleeve 1 surface and is conveyed by this, after which the separated toner 3 is allowed to make gravity fall from the isolating member 10 and is supplied again to the sleeve surface 1, whereby it is conveyed. Thereby, weak discharge is produced between the toner 3 and and sleeve 1, and this results in that all the charges of the toner 3 are once returned to zero.
