The IIO provides start position information to the print start position determining circuit 17, and corrects the horizontal positional deviation of each line head by shifting the effective image forming area on the line head within the upper recording element group arrangement range. becomes possible. In addition, by storing position information in the nonvolatile memory 11 backed up by a battery instead of using setting means such as a switch, it becomes easy to change the adjustment value.
Moreover, even if the power of the device is turned off, the adjustment position information can remain, and the information can be retained until readjustment is performed.
