    摘要: The present invention provides a method of and an apparatus for efficiently and economically discharging solid particles, which have sedimented on the bottom of a tank, out from the tank. A liquid is ejected from an ejector installed in the tank to move the sedimented solid particles to a predetermined place from which the sedimented solid particles are discharged out from the tank. Further, a solution which contains sedimentary solid particles is cooled and the solid particles are efficiently separated by a solid-liquid separator.

    摘要: A cleaning device for an electrostatic photographic copying machine having a sensitive drum provided with a paper-stripping groove at one side thereof includes an upper blade for stripping residual toner from the sensitive drum, a lower blade for guiding the thus stripped toner from the surface of the sensitive drum toward a toner withdrawing device, and a groove cover covering the paper-stripping groove at least from the upper blade to the lower blade so that the groove cover will be in contact with the lower blade. Residual toner which is stripped from the surface of the sensitive drum is prevented from entering the paper stripping groove by the groove cover.
