Abstract: PROBLEM TO BE SOLVED: To prevent the density of image from over increasing when the density of an output image is enhanced by writing a same imaging data twice onto a recording medium with ink being ejected from the nozzle of an ink jet head. SOLUTION: An ink jet printer 4 develops image information to be outputted into a bit map memory in the form of a raster data and the image information developed into the bit map memory is outputted onto a recording medium by ejecting ink from the nozzle of an ink jet head. When identical image information is written twice, the CPU 10 in the ink jet printer 4 writes the image information, as it is, by 100% for the first time imaging and writes the image information at a ratio selected between 0-100% for the second time imaging. The CPU 10 sets the imaging ratio the second time automatically depending on a recording medium being used. Further, an optical imaging ratio is selected for the second time imaging from the table of a controller based on the type of the recording medium being used and the imaging conditions, e.g. the temperature and humidity.
