Abstract
An image forming device includes a light emission controller that controls emission of a plurality of types of light emission patterns from a plurality of light sources. The light emission controller emits respective light emission patterns corresponding to the operation. When among the plurality of types of light emission patterns, the preceding light emission pattern overlaps with the subsequent light emission pattern, the light emission controller preferentially emits the subsequent light emission pattern having a delay in the light emission start timing. The light emission controller also emits respective first light emission patterns corresponding to the operation, and emits the second light emission pattern expressing the predetermined operation. When any type of emission of the first light emission pattern among the plurality of types of first light emission patterns overlaps with emission of the second light emission pattern, the light emission controller preferentially emits the second light emission pattern.
