An image forming apparatus and process cartridge that achieves extended operating life of a two-component developer without generating such problems as toner scattering, etc. either in the initial period or over time. The gap between the image support member and the developer support member is set to 0.3±0.1 mm. A substance having a resin cover layer on the surface of a core material is used as the carrier. The resin cover layer provides a conductive covering layer comprising a tin dioxide layer on the surface of base particles and an indium oxide layer, and comprises conductive particles formed such that the oil adsorption is 10 to 300 mL/100 g. A substance that provides a bonding resin comprising a hybrid resin having vinyl polymers and polyester polymers is used as the toner. The amount of hybrid resin contained in relation to the amount of releasing agent is set to the range of 0.5 to 3.
