PURPOSE:To convert to one layer and equalize exactly a filter particle without requiring high accuracy as to a blade by providing the blade for converting the filter particle to almost one layer and a high frequency vibrating means for vibrating mechanically the filter particle. CONSTITUTION:A filter particle scatter roller 16, a blade 17 for converting a filter particle to one layer, and a filter particle guide 18 for receiving a dropping filter particle are placed in a filter scatter device 7, and also a high frequency generator 19 is connected to a high frequency vibrating roller 4. This roller 4 and the generator 19 constitutes a high frequency vibrating means, and this means, the blade 17 and the guide 18 constitute a filter particle one layer-converting means. In the course of an operation of this single circulation type color electrophtographic copying machine, it is electrostatically charged uniformly by an electrifier 6, and thereafter, the filter particle is scattered onto the surface of a photosensitive body by the roller 16 of this device 7, and in this case, the filter particle is converted to almost one layer by the blade 17. |
