Embodiment Construction

[0080] (Powder Toner Conveying Method and Powder Toner Conveying Device)

[0081] The powder toner conveying method of the present invention fluidizes the powder toner by means of the gas supplied from the gas supply unit to the powder toner storage chamber, sucks the fluidized powder toner by means of the suction unit and Conveying powder toner by discharging the toner into a toner storage container,

[0082] Among them, a reciprocating pump is used to drive the suction unit to suck the powder toner.

[0083] A preferred aspect in this example is as follows: the gas supplied to the sealable, pressurized or non-pressurized powder toner storage chamber by the gas supply unit is regulated and introduced into the powder toner in the powder toner storage chamber a toner fluidizing unit, thereby fluidizing the powder toner in the powder toner storage chamber; suctioning the powder toner storage chamber through a suction inlet of the suction unit, thereby conveying the fluidized po...

Abstract

The present invention aims at providing a powder toner transferring method which fluidizes a powder toner with a gas supplied from an air supply means, sucks the fluidized powder toner with a suction means and transfers the powder toner by discharging the powder toner in a toner storage container, where the suction of the powder toner by means of the suction means is performed with a reciprocating-motion pump. The present invention also aims at providing a powder toner filling method that comprises the powder toner transferring process.

Description

field of invention [0001] The present invention relates to a powder toner conveying method for electrophotography and a conveying device thereof, a powder toner filling method and a filling device thereof, wherein the powder toner is fluidized by gas for conveying. Background technique [0002] Conventionally, a screw filling device using mechanical rotation is used to fill powder toner for electrophotography. [0003] External additives are generally adhered to the surface of toner for electrophotography to make fluidity higher. There are many cases in the conventional screw device that external additives adhering to the surface of the toner fall off, thereby causing quality problems. This problem has become more serious since toners having small particle diameters are recently used in order to obtain high-quality images compared with conventional toners. [0004] Regarding toner materials, external additives including silica and titanium and antistatic additives are adhe...
