A plurality of lasers (having openings 170) are formed at predetermined positions at equal intervals on at least two main scanning lines on a semiconductor substrate 100. The lasers have each a predetermined beam diameter and take different positions in the main scanning direction, thereby providing a two-dimensional surface emitting laser array emitting laser beams through a lens system to form a pixel line with no gap on the main scanning line of an image formation face moving in the sub-scanning direction. The two-dimensional surface emission laser array is used to provide a laser beam scanner, a laser beam recorder, and a laser beam recording method.

Column wirings are divided into at least two groups of first column wirings and second column wirings. Image data corresponding to different rows in one frame are supplied to these groups of column wirings at the single timing. At the same timing, row signals are applied to the different wirings at e.g. j=1 and j=17. Rows and columns can be replaced by each other.
