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.

摘要： In an image-forming device, a controller controls the value of an effective developer bias that is established between the electric potential of a latent image formed on an image bearing body and the electric potential of a developer bearing body, to thereby develop the latent image with a non-magnetic, single-component developer agent. The controller sets a target transmission density in a region in which the transmission density of the developer agent is in a proportional relationship with respect to the effective developer bias, and controls the value of the effective developer bias based on the target transmission density and the proportional relationship between the transmission density and the effective developer bias.

摘要： An image forming apparatus includes an image bearing body and a developer bearing body. A transferring section transfers, onto a medium, a developer image formed on the image bearing body by development of the latent image. A voltage applying section alternately applies, to the developer bearing body, a first voltage for making the developer move from the developer bearing body toward the image bearing body in order to develop the latent image, and a second voltage for making the developer move from the image bearing body toward the developer bearing body. An image darkness adjusting section adjusts a darkness of the image to be formed on the medium by changing only the second voltage.
