PROBLEM TO BE SOLVED: To perform such works as replacing a part or adjusting the position efficiently in a short time when a product is inspected or repaired at the time of shipment from a factory by grasping the cause of positional shift easily using a simple test pattern. SOLUTION: The imaging apparatus comprises a plurality of imaging units 24-1,..., 24-4, and a test pattern imaging control means 100 for controlling the first imaging unit 24-4 and the second imaging units 24-1,..., 24-3 to form a test pattern image where first and second marks having a density difference are contiguous to each other based on test pattern image data comprising first data for arranging a plurality of first color lines having a specified line width at a specified pitch by means of the first imaging unit 24-4, second data for forming the first mark while superposing on the plurality of first color lines by means of the second imaging units 24-1,..., 24-3, and third data for forming the second mark by shifting in the direction orthogonal to the plurality of first color lines. |
