Abstract
A developer remaining amount detecting apparatus of a developing apparatus for developing an electrostatic image on an image bearing body, includes a counter means for counting a number of an image data, an integrator means for integrating a using amount on the image bearing body, and operating section for operating a developer remaining amount on the basis of a count value of the counter and an integrated value of said integrator.
Claims9
A developer remaining amount detecting apparatus of a developing apparatus for developing an electrostatic image on an image bearing body, said detecting apparatus comprising:
- counting means for counting a number of an image data;
- integrating means for integrating a use amount on said image bearing body;
- and
- operating means for operating a developer remaining amount on the basis of a count value of said counting means and an integrated value of said integrating means.
A developer remaining amount detecting apparatus for a developing apparatus for developing an electrostatic image on an image bearing body, said detecting apparatus comprising:
- counting means for counting a number of an image data;
- recognizing means for recognizing an integrated use amount of said image bearing body without using the image data;
- and
- outputting means for outputting information regarding a developer remaining amount on the basis of a count value of said counting means and the integrated use amount recognized by said recognizing means.
