Abstract
An image forming apparatus includes an image forming unit, an image heating device, a filter, a display unit, and a controller. When an image forming operation of the image forming unit starts and an ambient temperature outside the image forming apparatus is a first temperature, the controller sets, after the image forming operation starts, a first period that begins after detected ambient temperature inside the image forming apparatus reaches a predetermined temperature and ends when filter replacement information is displayed on the display unit. When the image forming operation starts and the outside ambient temperature is a second temperature higher than the first temperature, the controller sets, after the image forming operation starts, a second period that is shorter than the first period and begins after the detected inside ambient temperature reaches the predetermined temperature and ends when the filter replacement information is displayed on the display unit.
