PROBLEM TO BE SOLVED: To provide an image forming method suppressing filming of toner on a toner carrier and suppressing an image defect by filming, even in intermittent printing for a long period of time at a low temperature and low humidity environment. SOLUTION: The image forming method comprises bringing a toner carrier directly into contact with the surface of an electrostatic latent image carrier to develop an electrostatic latent image on the surface of the electrostatic latent image carrier with the toner carried by the toner carrier, and is characterized in that: the toner carrier shows a MD-1 hardness of 20 to 60; the toner comprises toner particles, resin particles and inorganic fine power; the weight average diameter (D4r) of the resin particles is 2μm to 40μm; and the resin particles satisfy the relationship expressed by (1):0.15≤X<SB>20</SB>≤0.90 and (2):0.20≤Y≤0.85, wherein X<SB>20</SB>(μm) represents a displacement when one particle of the resin particles is loaded with 2.0×10<SP>-4</SP>N at a loading speed of 9.8×10<SP>-5</SP>/sec by a micro-compression testing machine, and Y (μm) represents an elastic displacement when the particle is loaded with 9.8×10<SP>-4</SP>N at a loading speed of 9.8×10<SP>-5</SP>/sec.
