Claim:
An image forming apparatus, comprising: an annular conveying path which is curved to have an annular shape; a plurality of image carrier rollers placed on an inner circumferential side of the annular conveying path so as to face the annular conveying path and so as to be juxtaposed in a sheet conveying direction along the annular conveying path; opposed rollers provided on an outer circumferential side of the annular conveying path so as to be in pressure contact with each of the image carrier rollers to constitute pairs of transfer rollers together with each of the image carrier rollers; imaging sections for forming intrinsic color images on surfaces of the respective image carrier rollers; and a control section for controlling so that a sheet is introduced to the annular conveying path and is passed sequentially through nip sections of the pairs of transfer rollers so as to be conveyed along the sheet conveying direction, while images, which are formed on surfaces of the respective image carrier rollers by the imaging sections, are transferred one by one onto the sheet, and the sheet with the images transferred thereon are released from the annular conveying path.
