PROBLEM TO BE SOLVED: To provide a portable image forming device which suppresses a position error accumulated in acquiring position information, calculates position information with high accuracy, and prevents deterioration of image quality.SOLUTION: A portable image forming device which forms an image while advancing in a predetermined direction of travel, includes: image forming means having a recording head; image detection means; position detection means; and correction means for correcting positional deviation. The recording head is disposed at an interval of a distance Xwith respect to the image detection means, and when the recording head forms an image pattern a, the position detection means detects position information a. The image detection means periodically reads an image to determine whether the image matches the image pattern a, and when they are determined to match each other, the position detection means detects position information b at the time when the image detection means detected the image pattern a. The correction means calculates a distance Xadvanced by the portable image forming device from the position information a and the position information b, and uses X-Xas a correction value to correct positional deviation. |
