1. A process cartridge comprising:
a photosensitive drum rotatable about an axis of thereof;
a first gear positioned coaxially with the photosensitive drum;
a coupling positioned at an end of the photosensitive drum and at a side of the process cartridge with respect to a direction of the axis of the photosensitive drum, the coupling being movable relative to the first gear and the photosensitive drum in the direction of the axis of the photosensitive drum, and the coupling being operatively connected to the first gear and the photosensitive drum so as to transmit a driving force to the first gear and the photosensitive drum;
a developing roller rotatable about an axis thereof, the developing roller being configured to develop a latent image formed on the photosensitive drum with toner;
a second gear positioned coaxially with the developing roller and engaging with the first gear, the second gear being operatively connected to the developing roller so as to transmit the driving force from the first gear to the developing roller;
a charging roller configured to charge the photosensitive drum;
a first frame supporting the photosensitive drum, the first frame having a projection projecting from the side of the process cartridge in the direction of the axis of the photosensitive drum;
a first electrical contact positioned on the projection of the first frame, the first electrical contact being electrically connected to the charging roller;
a second frame supporting the developing roller; and
a second electrical contact provided on the second frame at the side of the process cartridge, the second electrical contact being electrically connected to the developing roller,
wherein, as viewed along the axis of the photosensitive drum, the first electrical contact and the second electrical contact are positioned on opposite sides with respect to a line that passes through the axis of the photosensitive drum and the axis of the developing roller.
