を検出するものがある。BACKGROUND ART In this type of printing apparatus, the lifespan of a developing device is detected by detecting the number of toner replenishments. Conventionally, the method for detecting the number of times of toner replenishment is to press a detection switch when the toner cartridge is inserted into the main body, and count the number of times this detection switch is pressed. There is something that detects the number of times.

出となるという欠点がある。In this case, a protruding claw member for suppressing the detection switch is attached to the joint portion of the toner cartridge with the main body, and the number of times the detection switch is suppressed by the protruding claw member is counted. For this reason, even if a used toner cartridge is used, the detection switch is pressed by the protruding claw member and detected, resulting in an erroneous detection.

トナー補給回数検出機構が得られる。According to the present invention, there is provided a toner replenishment number detection structure in an electrophotographic printing apparatus configured to detect the number of toner replenishment times by pressing a detection switch for detecting the number of toner replenishment. The toner cartridge for replenishing toner has a diffraction claw member attached to the joint with the main body, so that the foldable member presses the detection switch when the car 1 to the cartridge are joined to the main body. Accordingly, there is obtained a toner replenishment frequency detection mechanism characterized in that the diffraction claw member is breakable.

has a foldable claw configuration. When the toner cartridge 3 is inserted into the developing device 4 of the apparatus main body 5, this foldable claw 1
The tip thereof presses the detection switch 2 attached to the main body 5 of the apparatus. Due to this pressing force, the detection switch 2 detects that the toner cartridge 3 has been inserted and toner has been replenished, and sends this detection output to a counting circuit (not shown).

るという効果がある。As described above, according to the present invention, a foldable claw is attached to the toner cartridge, the switch for detecting the number of replenishments is pressed by the claw, and the claw is then broken, so that the used cartridge can be removed. This has the effect of effectively preventing erroneous detection of replenishment.
