PROBLEM TO BE SOLVED: To provide a developing cartridge capable of balancing a force applied to a developing roller gear with a force applied to an electrode member when the image is formed to suppress its distortion, thereby preventing an image from being formed insufficiently, and to provide a process cartridge and an image forming apparatus to which the developing cartridge is attached. SOLUTION: The direction F1 of meshing force exerted to the developing roller driving gear 115 at a part where the developing roller driving gear 115 is meshed with a driving gear 101 in a gear mechanism part 92 provided on the left side wall 69L of the developing cartridge 30 and the direction F2 of pressing force exerted to a contact projecting part 122 of the electrode member 117 at a part where the winding part 167 of a developing bias applying electrode 164 comes into contact with the contact projecting part 122 in the electrode member 117 provided on the right side wall 69R thereof are set to nearly the same direction toward a rear side aperture part 73 on the upper part of the obliquely rear side thereof.
