The carbon powder box is fixed on the upper end of the bracket.

And a discharging blocking strip is arranged on the discharging opening of the toner cartridge, and the discharging blocking strip is tightly attached to the paper when the paper passes between the discharging opening and the electrostatic roller.

Still be equipped with the auxiliary roll that sets up with the parallel interval of static roller on the base, the axis of auxiliary roll and the axis of static roller are on the coplanar, and the auxiliary roll setting is in the anterior position department of static roller paper feed direction.

The end parts of the electrostatic roller and the auxiliary roller are respectively provided with a gear, the gears are meshed together in sequence, and when the motor drives the electrostatic roller to rotate, the auxiliary roller rotates under the transmission of the gears.

The utility model has the advantages that: the utility model discloses when using, send into the paper between static roller and the cartridge, the motor drives the static roller and rotates, makes the paper pass through between static roller and the cartridge, and the wire electrode in the static roller produces static, and the carbon dust in the cartridge is opened out from the cartridge and is located by the suction, therefore the carbon dust is evenly adsorbed to the paper surface, accomplishes the development process. Because the opening size of cartridge is invariable, the motor can guarantee that the static roller maintains invariable rotational speed, and the static size that the static roller produced is also controllable, consequently the utility model discloses can guarantee that the carbon dust distributes evenly on the paper, guarantee that the carbon dust quantity is invariable at every turn, guarantee the photographic fixing test result.

Preferably, a discharging blocking strip is arranged on a discharging opening of the carbon powder box, when the paper passes through the discharging opening and the electrostatic roller, the discharging blocking strip is tightly attached to the paper, so that the carbon powder is uniformly and slowly sucked out, the phenomenon that the sucked amount of the carbon powder is too large is avoided, and the paper can smoothly pass through the discharging opening.

Preferably, the auxiliary roller can help the paper smoothly pass through between cartridge and the static roller, can also play the effect of supporting the paper, prevents that the back paper that develops from dropping, leads to the carbon powder on the paper to drop.
