Abstract
An image forming apparatus, to which a cartridge including a developer accommodating portion for accommodating a developer is detachably mountable, includes an image bearing member, an exposure unit configured to expose the image bearing member to light to form an electrostatic latent image on the image bearing member, a light receiving sensor provided in the cartridge and configured to receive the light emitted from the exposure unit, and a controller configured to detect vibration of the cartridge from a light reception value of the light received by the light receiving sensor. In a case in which the cartridge is removed from the image forming apparatus, the light receiving sensor is removed from the image forming apparatus together with the cartridge.
