Abstract:
A laser imaging apparatus, comprising:a scanning unit that emits at least one scanning laser beam, which scans a surface to be scanned in a main scanning direction to form a scanning section, the at least one scanning laser beam being modulated in accordance with image data; a mover that moves the surface to be scanned in an auxiliary scanning direction, which is parallel to the surface to be scanned and different from the main scanning direction; a rotator that rotates the surface to be scanned about a predetermined rotation axis; a detector that detects a plurality of position marks provided on the surface to be scanned; a calculator that calculates an inclination of said scanning section with respect the main scanning direction, and that calculates a scaling factor of said scanning section with respect to a predetermined length in the main scanning direction based on a shape of the surface to be scanned, the shape being determined in accordance with the positions of said plurality of position marks; and an adjuster that adjusts a rotational position of the surface to be scanned in accordance with the inclination, and adjusts a start position of said scanning section on the surface to be scanned in accordance with said scaling factor.
