PURPOSE:To enable recording electrodes to be brought into constantly favorable contact with a printing medium and record images with high resolution and quality by cleaning the surface of the printing medium by a cleaning blade prior to pressing a printing head against the printing medium. CONSTITUTION:At the time of printing, a printing medium 3 fitted on feeding rolls is fed to a printing part by a driving means. Prior to the printing, a cleaning blade 2 is pressed against the surface of the printing medium 3, whereby cleaning is performed to remove dust and other foreign matter from the surface. As a result, contamination at a contacting part of a printing head is prevented from occurring, the diameter of printed dots is varied only in the range of + or -10%, and favorable printing can be maintained. |
