PROBLEM TO BE SOLVED: To provide an electrostatic charge image developing carrier, not causing leakage of charges on the surface even in a long-time use to maintain stable charge applying capability, an electrostatic charge image developer using it, and a process cartridge and an electrostatic charge image developer using the above. SOLUTION: This electrostatic charge image developing carrier includes a core material and a resin coating layer coating the core material, wherein Net intensity (M Net) based on various kinds of metal M according to fluorescent X-ray analysis satisfies the relationship expressed by following formula (1) and formula (2). The formula (1) is expressed by 0.8≤[(Al Net)/(Fe Net)] ×100≤2.5, ad formula (2) is expressed by 1.0≤(Al Net)/(Si Net) ≤2.5. COPYRIGHT: (C)2009,JPO&INPIT
