Method for forming an image
To provide an method for forming an image capable of effectively suppressing a toner from deteriorating and also capable of keeping the quality of an image for a long period of time, even when the method is applied to an apparatus with as high process speed. The prevent invention provides an method for forming an image, in which a developing unit is used, which includes: a rotatable cylindrical toner bearing member having a diameter represented as Rd (mm); and a rotatable cylindrical toner-supplying member having a diameter Rs (mm), the diameters Rd and Rs satisfying the following relational expression (1):1≦Rs−Rd≦10  (1)and in which the nonmagnetic one-component toner having an degree of aggregation of 5 to 30% and an electric resistivity of 1×1014 to 1×1018 Ω·cm at an electric field of 1×104 V/cm is used.
