PROBLEM TO BE SOLVED: To obtain an imaging apparatus having a plurality of resolutions and a plurality of process speeds in which any combination of ROS motor speed, Video Rate, spot power, and addressability in the subscanning direction can be confined within a specified range and addressability in the subscanning direction is not lower than a highest resolution for any combination. SOLUTION: Assuming the ratio of a highest resolution and a lowest resolution is N, and the ratio of a highest process speed and a lowest process speed is M (N and M are integers), the number of skipping the reflective face of a rotary polygon mirror, i.e., the number of line Skip, is selected such that the ratio of the highest value and the lowest value of all parameters comprising ROS motor speed, Video Rate, spot power, and addressability in the subscanning direction falls within a range of (N×N)/2. |
