Abstract
An image forming apparatus includes an apparatus body, a process unit having an image bearing member, a developer container configured to accommodate toner, a developing portion to develop an electrostatic latent image formed on the image bearing member into a toner image by using the toner accommodated in the developer container; and a replenishment port configured to allow replenishment of toner from the replenishment container, and a display portion. A controller notifies a user of information related to a toner amount by using the display portion in a case where it is determined that a lifetime of the process unit will expire before a sum of toner accommodated in the developer container and toner accommodated in the replenishment container is consumed, wherein the information related to a toner amount is a notification about toner, to be supplied from the replenishment container, which goes to waste.
