Abstract
A developer accommodating apparatus, a developing apparatus and an image forming apparatus are provided capable of obtaining detection stability of irregular reflection light. The developing apparatus of the present invention comprises an accommodating section to accommodate developer of predetermined quantity, a light emitting section to emit light toward outside; and a light shading section to shade the light emitted from the light emitting section according to the predetermined quantity of the developer in the accommodating section.
Claims17
A developing apparatus that is removably attachable to an image-forming apparatus, the developing apparatus comprising:
- an accommodating section to accommodate developer;
- a light emitting section to emit light toward the outside of said developing apparatus and toward a light-receiving section furnished in the image-forming apparatus when the developing apparatus is attached to the image-forming apparatus, the light-receiving section being disposed outside the developing apparatus;
- and
- a light shading section to shade the light emitted from the light emitting section according to a quantity of the developer in said accommodating section.
An image forming apparatus, comprising:
- a developing apparatus removably attached to the image forming apparatus and having an accommodating section to accommodate developer;
- a light receiving section that is furnished in the image forming apparatus, the light receiving section being disposed outside the developing apparatus;
- and
- a developer quantity detecting section,
- wherein said developing apparatus includes a light emitting section to emit light toward the outside of said developing apparatus;
- and
- a light shading section to shade the light emitted from the light emitting section according to a quantity of the developer in said accommodating section;
- wherein said light receiving section receives the light emitted from said light emitting section;
- and
- wherein said developer quantity detecting section detects the quantity of the developer in said accommodating section on the basis of the light received by said light receiving section.
A developer accommodating apparatus that is removably attachable to a developing apparatus and has an accommodating section to accommodate developer, comprising:
- a light emitting section to emit light toward the outside of said developer accommodating apparatus, and toward a light-receiving section that is disposed outside the developing apparatus;
- and
- a light shading section to shade the light emitted from the light emitting section according to a quantity of the developer in said accommodating section.
