Abstract
A thermosensitive recording printer is provided with semiconductor lasers 1a to 1c, a polygon mirror 7 for condensing laser light emitted from the semiconductor laser 1a to 1c as condensed spots on a recording medium 10 to perform scanning in a main scanning direction, and a control unit 9 for controlling the output of the laser light. If a ratio of a spot diameter D1 of the condensed spots in the main scanning direction and a spot diameter D2 in a sub scanning direction satisfy a relationship of D1/D2≦½ at the time of forming an image composed of a plurality of pixels on the recording medium 10 using laser light, high-speed thermosensitive recording and a recording method with an uncomplicated power control are realized without reducing the power density of the condensed spots.
