PURPOSE:To miniaturize and reduce the cost of an image forming device by reducing the density of magnetic flux of a revolving magnet. CONSTITUTION:A electromagnet 11 is provided in a position facing a conductor- exposed part 1c of a recording electrode 1 through a recording sheet 5. By energizing this with positive and negative exciting current from an inputting terminal 12 at the time of recording, the electromagnet 11 is energized to the reverse polarity to the magnetic pole of the revolving magnet 4 positioned directly below the conductor-exposed part 1c. Thus, by correction through application of magnetic flux density by the electromagnet 11 to the magnetic flux density necessary to carry toner 2, recording can be carried out by improving the stylus amount at the time of carrying of the toner to the required stylus amount for recording. Therefore, miniaturization can be attained by reducing the magnetic flux density of the revolving magnet 4, and recording at low cost and with good efficiency can be attained. Furthermore, by varying the size of the energizing current energizing the electromagnet 11, the stylus amount at the time of recording can be varied to control the image density. |
