該トナー担持体は、内側に固定マグネット、外側に回転可能なトナー搬送担持体で構成され、該トナー搬送担持体の表面粗さ面積を二分する平均値に対して、最大谷深さをRv、最大高さをRmaxとしたとき、下記式(1)で表される形状係数(K)が0.12以上0.50以下であるトナー担持体であり、
K=Rv/Rmax・・・(1)
該トナーが、少なくとも結着樹脂及び着色剤を含有するトナー粒子を有するトナーであり、該トナー粒子は、画像処理解像度512×512画素(1画素あたり0.19μm×0.19μm)のフロー式粒子像測定装置によって計測された円相当径0.25μm以上1.98μm以下のトナー粒子が、0個数%以上15.0個数%以下であることを特徴とする画像形成方法。 In an image forming method comprising at least a developing step of developing a latent electrostatic image formed on a latent image carrier with a toner carried on the toner carrier to form a toner image,
The toner carrier is composed of a fixed magnet on the inside and a toner transport carrier that is rotatable on the outside, and the maximum valley depth is Rv with respect to an average value that bisects the surface roughness area of the toner transport carrier. A toner carrier having a shape factor (K) represented by the following formula (1) of 0.12 or more and 0.50 or less when the maximum height is Rmax;
K = Rv / Rmax (1)
The toner is a toner having toner particles containing at least a binder resin and a colorant, and the toner particles are flow type particles having an image processing resolution of 512 × 512 pixels (0.19 μm × 0.19 μm per pixel). An image forming method, wherein toner particles having an equivalent circle diameter of 0.25 μm or more and 1.98 μm or less measured by an image measuring device are 0% by number or more and 15.0% by number or less .
