Abstract
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, and 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 …
