PURPOSE:To easily correct the printing output and to enable output with an expected printing density, when the output of the printing lower or higher than the expected printing density is obtained by outputting the calculated density difference to a printing part and resetting its density. CONSTITUTION:An image processing part 2 converts analog data transmitted from an image scanner part 1 into digital data and stores it and the printing part 3 prints data outputted from the image processing part 2 or a fixed density pattern output part 4. A fixed density data sampling part 5 calculates an average density value. A density comparing part 6 has the result of the printing when the fixed density pattern data of the fixed density pattern output part 4 is outputted to the printing part 3 and the expected density data and compares the data with the actually outputted average density data, to calculate the difference between the expected density data and the density data. When the density of the printing part 3 is reset by the density difference, the output with the expected printing density can be obtained. |
