A process cartridge includes a photosensitive drum, a rotatable developing roller, a rotatable toner supplying roller provided in contact with the developing roller, and a rotatable feeding member provided in a toner chamber and configured to feed the toner from the toner chamber. A coupling is operatively connected to the developing roller, the toner supplying roller, and the feeding member, with the coupling being configured to receive a driving force for rotating the feeding member, the developing roller, and the toner supplying roller. A plurality of gears are operatively connected to the developing roller, the toner supplying roller, and the feeding member, with each gear of the plurality of gears being configured to transmit the driving force received by the coupling to at least one of the feeding member, the developing roller, and the toner supplying roller.
