TONER SUPPLY CONTROL IN IMAGE FORMING APPARATUS BY USING LINEAR REGRESSION ANALYSIS

摘要

An example operation method of an image forming apparatus includes obtaining, through a sensor in the image forming apparatus, toner data corresponding to an amount of toner remaining in a developing apparatus, obtaining, based on the toner data in every predetermined period, a linear prediction model predicting the amount of toner remaining in the developing apparatus according to a time at which the toner is supplied to the developing apparatus, predicting, based on the linear prediction model, an expected supply time required for the amount of toner remaining in the developing apparatus to reach a target level, and controlling an operation of supplying the toner to the developing apparatus according to a result of comparing the expected supply time with a predetermined reference supply time.
