POWDER TONER, MEANS OF HOUSING THE SAME AND METHOD FOR SUPPLYING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for efficiently supplying a powdery toner from a toner housing vessel which is filled with the powdery toner and whose volume can be reduced to the developing part of an image-forming apparatus. SOLUTION: A vessel which is produced from a flexible material and whose volume can be reduced by >=60% is filled with a powder toner, having <=500 ppm residual monomer content, and the toner is sucked together with a flow of air by a suction pump, transferred and then introduced into the developing part of an image-forming apparatus.
