An image forming apparatus which forms an image by using toner from a toner container mounted thereto. Consumption data is acquired, related to a toner consumption amount of the image forming apparatus, and based on the consumption data there is a determination of the number of remaining days until a predicted date in which a replacement of the toner container mounted onto the image forming apparatus is predicted. The number of the remaining days is displayed; however, the number of the remaining days is not displayed until a condition is satisfied related to the number of sheets on which images are formed by the image forming apparatus, wherein the condition is satisfied in a case where the number of sheets on which images are formed by the image forming apparatus is more than a predetermined number of sheets.

An image forming apparatus including a consumable to be used for image formation. The image forming apparatus includes: a usage amount detector configured to detect a cumulative value of a usage amount of the consumable and a remaining amount of the consumable; a predictor configured to predict a period that allows use of the consumable based on the remaining amount detected by the usage amount detector; and a determination unit configured to generate a delivery request signal for prompting a delivery request for the consumable when the period that allows the use predicted by the predictor is smaller than a predetermined number-of-day threshold value. The image forming apparatus avoids performing processing for generating a delivery request signal by the determination unit after the start of the use of the image forming apparatus until a predetermined condition is satisfied.
