摘要： The method for manufacturing a color print by an electrophotographic image forming process employs forming toner images by non-contact developing electrostatic latent images on electrostatic latent image holding members in developing devices. For each color, cyan, magenta and yellow, there is a separate electrostatic latent image, a separate electrostatic latent image holding member and a separate developing device. In each developing device the holding member is arranged in a non-contact position with respect to the electrostatic latent image holding member at a development portion. The non-contact developing is carried out by flying the toner from the toner holding member to the electrostatic latent image holding member. The cyan toner exhibits a maximum chroma at lightness L*C of from 53-70.
