Color image forming apparatus

摘要

A color image recording apparatus records color images on a recording medium and includes a plurality of image forming media and respective devices for forming respective images each of a different color on each of the image forming media. Transfer apparatus are provided for transferring the images respectively formed on the media onto a recording medium which is conveyed past the image forming media and the transfer apparatus by a recording medium conveyor. A detector generates a position signal that indicates that the recording medium is at a predetermined position on a predetermined path upstream of the first image forming medium, the image on which is to be first transferred to the recording medium. A circuit designates an area on the recording medium to which the respective images are to be transferred and a controller controls the start timing of the formation of a respective image on the first image forming medium by the image forming device in accordance with the position signal generated by the detector and the area on the recording medium designated by the designating circuit. Thus, transfer of the respective color images to the designated area on the recording medium is accomplished in proper registration so that a clear color image is produced.
