Toner supply device

摘要

According to one embodiment, a toner supply device includes a motor and an estimating unit. The motor rotates a toner container that supplies a toner to an image forming apparatus. The estimating unit estimates a toner residual amount in the toner container at a second point in time on the basis of a total rotation time representing time in which the motor rotates in a period of use from a first point in time when the toner container is attached to the image forming apparatus to the second point in time.

1. A toner supply device comprising:
a motor configured to rotate a toner container that supplies toner to an image forming apparatus; an estimating unit configured to estimate a toner residual amount in the toner container at a second point in time on the basis of a total rotation time representing time in which the motor rotates in a period of use from a first point in time when the toner container is attached to the image forming apparatus to the second point in time; and a detecting unit configured to detect a number of revolutions per unit time of the motor, wherein the estimating unit corrects the total rotation time on the basis of the number of revolutions per unit time detected by the detecting unit and estimates the toner residual amount on the basis of the corrected total rotation time.
