PROBLEM TO BE SOLVED: To provide an image forming device that can efficiently store an APC pattern and control consumption of a storage area.SOLUTION: An image forming device (100) has a plurality of light sources 302 which irradiate laser light to an image carrier to be rotation-driven and a PD211 that receives the laser light irradiated from the light sources respectively and converts the light into electric information. The image forming device also has a laser driver 403 that when adjusting driving current amounts to be applied to the light sources respectively on the basis of the electric information and a reference light quantity, adjusts the driving current amounts so that feedback control is converged in a predetermined time. Further, the image forming device has a RAM410 which stores an adjustment pattern for adjustment to be performed by the laser driver, where in the RAM are stored tables, in which are prescribed respectively light sources, light emission patterns of the light sources and adjustment execution times which are adjusted as adjustment patterns, in association with one another.SELECTED DRAWING: Figure 4 |
