Abstract
A developing cartridge for detachable mounting in an imaging device having a power supply component has: a housing having a driving side and an opposite side of the driving side in a first direction; a developing roller rotatably supported by the housing, configured to be rotatable about an axis extending in the first direction; a supply roller rotatably supported by the housing and configured to convey a developer to the developing roller; a doctor blade supported by the housing and configured to control a thickness of a developer layer on the developing roller; a driving gear on the driving side and configured to receive driving force from outside the developing cartridge and rotate; a detected component located on the opposite side; a power receiving component on the opposite side. The power receiving component can touch the power supply component to receive power and is electrically connected to the doctor blade.
