1. A process cartridge comprising:
a photosensitive drum;
a developing roller configured to develop a latent image formed on the photosensitive drum;
a coupling including a driving force receiving portion and a driving force transmitting portion, the coupling being operatively connected to the developing roller so that the coupling is capable of transmitting a driving force from the driving force receiving portion to the developing roller through the driving force transmitting portion;
a toner supplying roller in contact with the developing roller, the toner supplying roller being configured to supply toner to the developing roller;
a toner chamber containing the toner;
a developing chamber in which the toner supplying roller is positioned; and
a feeding member positioned in the toner chamber,
wherein the driving force receiving portion is movable relative to the driving force transmitting portion in a direction crossing an axis of the driving force receiving portion such that a position of the axis of the driving force receiving portion relative to an axis of the driving force transmitting portion is changeable, and
wherein, when the process cartridge is oriented with the photosensitive drum and the developing roller positioned at an upper part of the process cartridge, (i) the developing chamber is positioned above the toner chamber, and (ii) the feeding member is configured to feed the toner upward from the toner chamber to the developing chamber.
