Dynamics of Pin Electrode in Pin-to-plate Gas Discharge System Used for Ozone-less Charger in Laser Printer
2002
Dynamics of a pin electrode in a pin-to-plate discharge system have been investigated to realize a new ozone-less charger of a laser printer. Vertical coupled vibration of the pin electrode was observed when the spark discharge took place. The force applied to the pin electrode at the spark discharge was implicitly evaluated and it was elucidated that the force was attractive, in the order of 1 mN, and it became large in accordance with the increase of the applied voltage. The frequency of the vibration was smaller than the natural frequency of the pin electrode. The force at the positive discharge was larger than that at the negative discharge but the decrease of the vibration frequency at the positive discharge was smaller than that at the negative discharge.
