Abstract
When a space region shorter than the radius of a beam spot is formed, pre-heating with an assist pulse is not performed, and an off pulse pattern is fixed at a base power level. When a space region longer than the radius of the beam spot and shorter than the diameter of the beam spot is formed, an assist pulse is applied to the end of the space region to be formed. The length of the assist pulse is made greater, the longer the space region to be formed. Further, when a space region longer than the diameter of the beam spot is formed, an assist pulse is applied to the end of the space region to be formed, and the length of the assist pulse is kept constant regardless of the length of the space region to be formed.
