Abstract (en)
An image forming apparatus includes a conveyor (201), head units (310a, 310b, 310c, 310d), edge sensors (312a, 312b, 312c, 312d), an actuator (311b, 311c, 311d), a memory (416), and a controller (417). The edge sensors (312a, 312b, 312c, 312d) are arranged in correspondence with at least two sensor-corresponding head units of the head units, to detect edge positions of the recording medium in a direction perpendicular to a conveyance direction of the recording medium. The actuator (311b, 311c, 311d) moves at least one actuator-driven head unit of the sensor-corresponding head units in the direction perpendicular to the conveyance direction. The memory (416) stores reference values generated in advance based on data on the edge positions read by the edge sensors. The controller (417) controls the actuator according to the edge positions read by the edge sensors and the reference values to correct a position of the actuator-driven head unit.
