Abstract
An image forming apparatus at least includes: a component, detachable from the image forming apparatus, including a driven portion; first and second detectors configured to detect an installation of the component in the image forming apparatus and driving of the driven portion, respectively; an indicator device configured to communicate information to a user; and a controller to control the indicator device. In a circumstance in which neither an occurrence of installation nor driving of the driven portion are detected, the controller outputs a first notification requesting a proper installation of the component when a first count of occurrences of the first notification or a second count of occurrences of cancellation of the first notification is less than first and second reference values, respectively, and a second notification requesting repair when the first count or the second count equals the first and second reference values, respectively.
