    • An image forming method has the steps of forming a toner image by developing through a developing means a latent image formed on a latent image bearing member; transferring the toner image formed, from the latent image bearing member to a transfer medium through a transfer means to which a bias is applied; cleaning the latent image bearing member from which the toner image has been transferred to the transfer medium, to recover and collect the toner remaining on the latent image bearing member; and feeding the toner recovered and collected, to the developing means for reuse in the developing step. The toner has a binder resin and at least one of a magnetic powder and a colorant. The toner has a weight average particle diameter (D.sub.4) of from 4 .mu.m to 11 .mu.m; a coefficient A of variation of number-base distribution, of not more than 40, which is a coefficient represented by the formula: A=S.sub.n /D.sub.1 .times.100 wherein S.sub.n represents a standard deviation of number-base distribution, and D.sub.1 represents a length average particle diameter (.mu.m) on the basis of number; and a coefficient B of variation of volume-base distribution, of not more than 30, which is a coefficient represented by the formula: B=S.sub.W /D.sub.4 .times.100 wherein S.sub.W represents a standard deviation of volume-base distribution, and D.sub.4 represents a weight average particle diameter (.mu.m) on the basis of weight.
    • 图像形成方法具有以下步骤:通过显影装置显影形成在潜像承载部件上形成的潜像来形成调色剂图像; 通过施加偏压的转印装置将形成的调色剂图像从潜像承载部件转印到转印介质上; 清洁调色剂图像已经转印到转印介质上的潜像承载部件,以回收和收集残留在潜像承载部件上的调色剂; 并将回收和收集的调色剂进料到显影装置中以便在显影步骤中重复使用。 调色剂具有粘合剂树脂和磁性粉末和着色剂中的至少一种。 调色剂的重均粒径(D4)为4〜11μm; 数字分布的变化系数A为40以下,其为由下式表示的系数:A = Sn / D1×100,Sn表示数碱基分布的标准偏差,D1表示长度平均粒径 (亩); 和体积基础分布的变化系数B为30以下,其为由公式B = SW / D4×100表示​​的系数,SW表示体积基础分布的标准偏差,D4表示重均粒子 基于重量的直径(μm)。
