Abstract
Official abstract text for this publication.
An electrophotographic image forming apparatus includes an imaging cartridge and a toner cartridge that are detachably attached to a main body, a first optical sensor that is mounted in the imaging cartridge and detects a toner level in a development chamber, and a second optical sensor that is mounted in the toner cartridge and detects a toner level in the development chamber.
First claim
Opening claim text (preview).
What is claimed is: 1. An image forming apparatus comprising: a main body; an imaging cartridge comprising a photoreceptor, a development chamber, and a development roller to supply toner from the development chamber to the photoreceptor to develop an electrostatic latent image on the photoreceptor, wherein the image cartridge is detachable from the main body; a toner cartridge, detachable from the imaging cartridge, to contain toner; a first optical sensor mounted in the im…
