    • An image-forming method is comprised of delivering a transfer-receiving medium to a first image-forming unit, forming a first toner image by a first image-forming means of the first image-forming unit, transferring the first toner image onto the transfer-receiving medium at a first transfer section of the first image-forming unit with a first transfer bias applied, delivering the transfer-receiving medium to a second image-forming unit, forming a second toner image by a second image-forming means of the second image-forming unit, transferring the second toner image onto the transfer-receiving medium carrying the first toner image at a second transfer section of the second image-forming unit with a second transfer bias applied, fixing the first toner image and the second toner image transferred on the transfer-receiving medium by a fixing means. The length of the transfer-receiving medium in the direction in which the transfer-receiving medium is conveyed is larger than the spacing between the first transfer section and the second transfer section. The intensity of the second transfer bias is different from the intensity of the first transfer bias. A first toner for forming the first toner image and a second toner for forming the second toner image both have shape factors of SF-1 ranging from 100 to 180 and SF-2 ranging from 100 to 140.
    • 图像形成方法包括将转印接收介质输送到第一图像形成单元,通过第一图像形成单元的第一图像形成装置形成第一调色剂图像,将第一调色剂图像转印到转印 在第一图像形成单元的第一传送部分接收第一图像形成单元的第一图像形成装置,其中施加有第一转印偏压,将转印接收介质输送到第二图像形成单元,通过第二图像形成装置形成第二调色剂图像 第二图像形成单元,在施加第二转印偏压的情况下,将第二调色剂图像转印到第二图像形成单元的第二转印部分上承载第一调色剂图像的转印接收介质上,固定第一调色剂图像和第二调色剂图像 通过固定装置在转印接收介质上转印的图像。 传送接收介质在传送接收介质的传送方向上的长度大于第一传送部分和第二传送部分之间的距离。 第二转印偏压的强度不同于第一转印偏压的强度。 用于形成第一调色剂图像的第一调色剂和用于形成第二调色剂图像的第二调色剂都具有从100至180的SF-1的形状因子和100至140的SF-2。
