Abstract
The image forming device includes a main body and a cartridge that is detachably mountable on the main body. The cartridge includes the image bearing member, the first and second cleaning roller, and the state changing unit. The first cleaning roller cleans the image bearing member and the second cleaning roller cleans the first cleaning roller. The state changing unit is configured to irreversibly change an electrically disconnected state between the first cleaning roller and the second cleaning roller into an electrically connected state between the first cleaning roller and the second cleaning roller. The resetting unit is configured to reset the cumulative value when the current detecting unit does not detect current before the image bearing member rotates and detects current after the image bearing member rotates.
