Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent resonance of a control electrode by deviating a phase of a driving frequency of the electrode by applying a voltage from a phase of a resonance frequency of the electrode. SOLUTION: When a signal voltage based on an image to be formed on a control electrode 12 to form a toner image on a recording medium 3 is continuously applied in the case of forming the image by a recording head, electrostatic force operating near the electrode 12 is changed, the electrode 12 is vibrated so that a direction for the toner to fly is deviated from a target position. Then, to prevent the resonance, a phase of the frequency of the generated vibration is deviated from that of a resonance frequency of the electrode 12. That is, when a driving frequency of a brushless motor such as a stepping motor of a driver for driving a roller is set to 1.01 kHz, its about 4.95 times becomes a driving frequency of a dot, and its about 20.2 times as large as the driving frequency of a line becomes a driving frequency of the brushless motor to prevent resonance of the electrode 12.
