Abstract (en)

An electrostatographic imaging process and apparatus is described wherein a multi color image is formed by the transfer to a receiver of a set of colored toner compositions and fixing of the entire set of colored toner compositions transferred to said receiver characterised in that at least once and according to a preferred mode, after each transfer to said receiver of a colored toner composition and before the transfer to said receiver of the subsequent colored toner composition, a sintering of the transferred colored toner composition unto said receiver is executed. The electrostatographic imaging process may either be a xerocopying or xeroprinting process, whilst the sintering is preferentially executed by the application of the flash fusing process, e.g. by a Xenon flash lamp, and the final fixing is preferentially executed by the application of the heated roller fusing process.
