摘要： PROBLEM TO BE SOLVED: To shorten the time up to completion of a startup of a system by preventing control data which is not necessary for light quantity control over a light source from being set again in an image formation apparatus that sets control data, characteristic of a light beam scanner, stored in a nonvolatile memory of the light beam scanner and including light quantity control data in a register and uses the control data for illumination control over the light source.SOLUTION: A non-reboot area and a reboot area are set in a nonvolatile memory 109, control data needed only when a power source is turned on and when a unit is replaced, for example, an adjustment value for a write unit, an LD current value for a process, etc., are stored in the non-reboot area, and light quantity control data is stored in the reboot area. When the power source is turned on, a light source control part 104 reads the control data out of the non-reboot area and reboot area, and sets the control data of the reboot area in internal registers. When the internal registers are cleared as a door is opened and closed, the light quantity control data is read out of the reboot area and set again in the internal registers.
