摘要： A method of controlling the position of nozzles in an ink-jet type image forming apparatus. Positional information for the nozzles at the time of print-driving the image forming apparatus is calculated by combining a first positional information with a second positional information, wherein the first positional information is measured with reference to a nozzle plate and then recorded as reference information from among various positional information for an effective detection area, which is defined as an area on a print medium measured by a light receiving part of the detection sensor in terms of the amount of reflected light. The second positional information for the effective detection area is measured with reference to a predetermined position of the print medium at the time of print-driving and is variable depending on the movement of the nozzle plate. Accordingly, the relative positional information for the nozzle plate can be accurately set, thereby more accurately controlling the position of the nozzle plate.
