Abstract
An image forming apparatus includes a toner replenishing device that supplies toner, based on a detection result from a sensor that detects a toner density in a developing device that develops an electrostatic latent image based on an image signal with toner, so that the toner density takes a given value, a memory portion that counts a time for toner replenishment actually carried out by the toner replenishing device to accumulate count results as an accumulated actual toner replenishment time, a memory portion that calculates an expected required time for toner replenishment based on the image signal to accumulate calculation results as an accumulated expected toner replenishment time, and a determining portion that determines in given timing whether or not to execute the image quality adjusting processing, based on a difference between the accumulated actual toner replenishment time and the accumulated expected toner replenishment time.
