Abstract
In an electrophotographic image forming apparatus to which a cartridge containing a developer therein is detachably attachable, the cartridge has storing means storing therein information regarding the cartridge, and the main body of the apparatus is of a construction which has two or more means for relating the output of developer remaining amount detecting means and the developer amount to each other, and determines the means for relating the output of the developer remaining amount detecting means used to detect the developer amount from the output of the developer remaining amount detecting means and the developer amount to each other, on the basis of the information regarding the cartridge stored in the storing means
Claims22
An image forming apparatus to which is detachably attachable a cartridge having a developer containing portion and developer remaining amount detecting means capable of sequentially putting out an output conforming to a developer amount in said developer containing portion,
- wherein said cartridge has storing means storing therein information regarding said cartridge, and
- wherein a main body of said apparatus has two or more means for relating the output of said developer remaining amount detecting means and the developer amount to each other, and the means for relating the output of said developer remaining amount detecting means used to detect the developer amount from the output of said developer remaining amount detecting means and the developer amount to each other are determined on the basis of the information regarding said cartridge stored in said storing means.
A cartridge comprising a developer containing portion;
- developer remaining amount detecting means capable of sequentially putting out an output conforming to the developer amount in said developer containing portion;
- and storing means storing therein information regarding said cartridge.
An image forming system for forming an image on a recording medium by use of a cartridge detachably attachable to a main body of an image forming apparatus, comprising:
- (a) a cartridge having a developer containing portion, developer remaining amount detecting means capable of sequentially putting out an output conforming to the developer amount in said developer containing portion, and storing means storing therein information regarding said cartridge;
- and
- (b) control means having two or more means for relating the output of said developer remaining amount detecting means and the developer amount to each other, and determining the means for relating the output of said developer remaining amount detecting means used to detect the developer amount from the output of said developer remaining amount detecting means and the developer amount to each other, on the basis of the information regarding said cartridge stored in said storing means.
