Abstract
PURPOSE:To satisfactorily diffuse toner particles in a developer, and also, to continuously disperse said toner particles into the developer, by dispersing only the toner particles which have been finely pulverized by a rotary blade, into a developer tank through a mesh. CONSTITUTION:At the time of replenishing toner particles, a pump 52 starts, and also, by a start of a motor, a blade 55 rotates at a high speed. In this state, the toner particles which have been led into a casing 50 through a pipe 51 from a replenishing tank 53 through the pump 52 is in a high viscosity state since it has a high degree, but pulverizing instantaneously by a rotation of the blade 55, becomes a single toner particle group, dropped down into a developer tank 5F from a mesh 57 and diffused in a developer, and stirred by an agitator 58. On the other hand, a lump-like toner particles which have not been pulverized instantaneously even by the blade 55 does not pass through the mesh 57 but stays in the casing 50, but finely pulverized gradually by a time elapsing rotation of the blade 55 and becomes a state that it can pass through the mesh 57.
