PROBLEM TO BE SOLVED: To provide powder toner supply technique by which the automatic supply of powder toner that the powder toner is not suspended in the air is realized and which uses a powder toner storing means capable of being recovered in a compact state by constituting a container of flexible material and folding it after its use, that, is the technique by which the supply amount of the powder toner is made stable, the packing of the powder toner in the container after preservation is prevented and further the residual amount of the powder toner is made small. SOLUTION: This powder toner supply method is a method for supplying the powder toner to the developing means of an image forming device for developing an electrostatic latent image or a magnetic latent image with the powder toner. In the method, a toner replenishing device equipped with the toner storing means which can be coupled with a pump means for automatically supplying the toner to the developing means of the image forming device is used, and the average number molecular weight Mn of the toner with which the power toner storing means is filled is 2000 to 7000. |
