<p>PURPOSE:To easily reuse the used dry electrophotographic toner vessel by forming a vessel for supplying a magnetic toner or a waste magnetic toner vessel out of a thermoplastic resin contg. a magnetic substance. CONSTITUTION:A magnetic toner vessel or a waste toner vessel in a cleaning process is formed out of a thermoplastic resin mixed with a magnetic substance. The triiron tetroxide, gamma-iron sesquioxide, tricobalt tetroxide, etc., having 0.1-1.0mum grain diameter are used as the magnetic substance. When the vessel is reused, the triiron tetroxide as the essential material of a magnetic toner is advantageously used. As the magnetic substance is mixed, the sp.gr. of the vessel is identical to that of the toner depositing on the vessel or waste toner, and the vessel is uniformly mixed with the waste toner when recycled. Further, the strength of the vessel is improved by mixing the magnetic substance.</p> |
