An image reader is provided, which includes a light-emitting-timing setting unit configured to divide a non-light-emitting time during which none of light sources emits light in a predetermined reading period into a plurality of segmental non-light-emitting times and set a light-emitting moment separately for each light source as a moment to emit the light in the predetermined reading period, such that the segmental non-light-emitting times are arranged in a dispersed manner in the predetermined reading period, and a controller configured to control each light source to emit the light during a light-emitting time determined separately for each light source at the light-emitting moment set by the light-emitting-timing setting unit. |
