Abstract: An image forming apparatus includes an acquiring unit configured to acquire atmosphere pressure in the installation place of the image forming apparatus, photoconductors, light sources configured to radiate laser light, and a polygon mirror configured to be rotatable. The polygon mirror exposes the photoconductors by reflecting the laser light toward the photoconductors while rotating. The image forming apparatus further includes a control device configured to control rotation of the polygon mirror. The control device outputs an enable signal for allowing the image forming apparatus to perform printing, if rotation of the polygon mirror is stabilized after start of the rotation, and advances the timing of outputting the enable signal as the atmosphere pressure increases.
