Abstract
A management system includes: an image forming apparatus including a toner storage unit storing toner used in a developing unit, and a toner-transporting unit transporting the toner from the toner storage unit to the developing unit; and a management device connected to the apparatus through a communication unit, and managing a toner-remaining amount in the toner storage unit. The management device includes: an acquiring unit acquiring, from the apparatus, information on toner transportation time and characteristic quantities concerning variation in toner consumption in the developing unit and representing environment in the apparatus; a predicting unit calculating a predicted value of the toner-remaining amount with the acquired information on toner transportation time; a memory storing correspondence between the predicted value and a measured value of the toner-remaining amount; and a correcting unit correcting the correspondence according to the characteristic quantities, and correcting the predicted value with the corrected correspondence.
