Image forming apparatus which determines a toner supplying amount based on predicted toner consumption and predicted density of stored toner, toner supply method, and non-transitory computer-readable recording medium encoded with toner supply program

Abstract

An image forming apparatus includes an image former which forms an image on an image carrying member with toner stored in a storage, a toner supplier which supplies toner to the storage by driving a conveyance member, a density measurer which causes the image former to form an image having a predetermined density at a predetermined timing and measures density of the formed image, a corrector which corrects a driving amount of the conveyance member based on the density measured by the density measurer, and a changer which changes a timing when the density measurer measures the density in response to an event that a predetermined condition is satisfied.
