PROBLEM TO BE SOLVED: To provide an image forming apparatus and an image forming method in which even after outputting several ten thousand images, cohesive property in toner transfer compression or after stressing in a developing machine and adherence between toner particles are properly controlled and excellent transferability, developability and fixability are exhibited, and a high-quality image slightly dependent on the quality of a transfer material can be formed stably. SOLUTION: A toner for electrostatic image development including at least a binder resin and a colorant is provided, wherein when the toner is compressed at 15 kg/cm<SP>2</SP>, interparticle force is 1.0×10<SP>-9</SP>-1.0×10<SP>-6</SP>N, compressive adherence is 20-100 gf and compressive bulk density is 300-800 kg/cm<SP>3</SP>.
