Abstract: PROBLEM TO BE SOLVED: To make resolution of an image high even when resolving power of a printing heat is low by an apparatus wherein vibration is generated in the printing head and a plurality of basic raster lines are set on the surface of an image carrier and an additional raster line is set on each space between the basic raster lines and dots are formed on both lines. SOLUTION: When a sensitized body drum is exposed to light by an LED head 11 and a sine wave electric voltage is applied on a piezoelectric element 31 by a high voltage electric power, the head is moved to a spring 32 side and is contracted and an energizing force is generated in the direction where the head 11 is returned to the piezoelectric element 31 side. At this point of time, when application of the electric voltage on the piezoelectric element 31 is stopped, vibration in the line direction is generated in the head 11 by energizing force of the spring 32. By making an LED element 52 emit light in following to an actual printing data signal on the max. and the min. parts of this vibration, an additional raster line is set between basic raster lines set in the line direction of the sensitized body drum and dots are formed on both lines.
