ABSTRACT:
An image forming device includes a container accommodating toner, a light emitting unit emitting light to be transmitted through the container, a light receiving unit receiving the light transmitted through the container, an efficiency determining unit determining a light receiving efficiency based on a light intensity of the light received by the light receiving unit, an execution amount determining unit determining an execution amount of image forming operations that represents an accumulated amount of image forming operations executed since first use of the container, a correction coefficient determining unit determining a correction coefficient based on the execution amount of image forming operations, an efficiency modifying unit modifying the light receiving efficiency with the correction coefficient, and an estimating unit estimating an amount of the toner remaining in the container based on the modified light receiving efficiency.
