Abstract
An image forming apparatus is provided. A development cartridge having a first memory storing therein cartridge information is detachably mountable to the image forming apparatus. The image forming apparatus includes: an apparatus casing and an exposure unit having plural light emitting portions. The exposure unit is supported by the apparatus casing so that the light emitting portions face a photosensitive member rotatably supported by the apparatus casing. The image forming apparatus further includes a reader unit disposed on the exposure unit and configured to read the cartridge information from the first memory when the development cartridge is mounted to the image forming apparatus.
Claims9
An image forming apparatus, to which a development cartridge is configured to be detachably mounted, the development cartridge having a first memory storing therein cartridge information, the image forming apparatus comprising:
- an apparatus casing having a cover;
- an exposure unit having plural light emitting portions, the exposure unit being supported by the apparatus casing so that the light emitting portions face a photosensitive member rotatably supported by the apparatus casing;
- a reader unit disposed on the exposure unit and configured to read the cartridge information from the first memory when the development cartridge is mounted to the image forming apparatus;
- and
- a determining unit configured to determine both of an opening/closing state of the cover and a mounting state of the development cartridge based on whether or not the reader unit can read the cartridge information,
- wherein the exposure unit is a light emitting diode unit and the light emitting diode unit is attached on the cover.
