PURPOSE:To restrain the number of drivers and manufacturing cost and prevent damage to pattern and short circuit so as to improve reliability of a device and easily manufacture it by providing high resolution for a direct type electrostatic printing device, preventing a control electrode and a connecting terminal pattern from becoming minute, and reducing the number of connections of the control electrode and the drivers. CONSTITUTION:A control electrode comprises first electrodes 23 formed on a first face of an insulating substrate 21 separately, second electrodes 24 formed on the second face of the insulating substrate 21 separately and in a way traversing the first electrodes 23 obliquely, apertures 22 formed at the crossing parts of the first electrodes 23 and the second electrodes 24, and signal supplying connection terminals 25, 26 connected to each of the first and second electrodes 23, 24 and pulled out in one direction. By using the control electrode, the second electrodes 24 are operated to control electric field by time sharing at every first electrode 23. Thus, in a direct type electrostatic printing device, a toner is flown through the apertures 22 so as to form a toner image on a print medium, fixed, and an image is printed. |
