Abstract:
A device for determining an end of life of an organic photoreceptor includes a potential detecting unit that detects a residual potential of the organic photoreceptor, a temperature detecting unit that detects temperature of the organic photoreceptor in either one of a direct manner and an indirect manner, and a life determining unit that determines the end of life of the organic photoreceptor based on the residual potential detected by the potential detecting unit and the temperature detected by the temperature detecting unit.
