TRANSFERRING METHOD AND TRANSFERRING APPARATUS OF POWDER TONER FOR ELECTROPHOTOGRAPH, FILLING METHOD, AND FILLING APPARATUS

PROBLEM TO BE SOLVED: To provide a transferring method and a transferring apparatus having high capabilities, which transfer a powder toner without giving stress and do not pressurize the powder toner or reduce pressurization as much as possible when transferring and are free from jamming of the powder toner and employ a light-weight and small-sized portable transferring means for intermittent suction and allow any supply voltage to be available on demand, and also to provide a method and apparatus which uses the transferring method and the transferring apparatus to precisely and efficiently fill a soft container with the toner with a high density while suppressing powdery dust. SOLUTION: In the powder toner transferring method comprising a powder toner suction means and a means for gas supply to the powder toner, a gas is supplied into a toner storage container having the powder toner stored therein, and the powder toner fluidized by the gas is sucked by the powder toner suction means and is discharged out of the toner storage container and is transferred. A reciprocating-motion pump is used for powder toner suction by the powder toner suction means. COPYRIGHT: (C)2007,JPO&INPIT
