摘要： A first negative or positive latent electrostatic image is formed on a latent image bearing body with a first writing device, and developed with a monochromatic toner. A second latent image of the type different than the first latent image is formed by a second writing device after setting the background voltage of the second image to have an absolute value larger than the first image, and then developed with one or two color toners selected from three color toners of respective multi-color developing units. A plurality of multi-color toner images may be formed in respective rotation cycles of the latent image bearing body. A monochromatic toner image may be formed in the same rotation cycle as one of the multi-color toner images. Finally, a plurality of toner images thus produced are transferred onto a recording sheet at once after polarities of the plurality of toner images have been arranged into the same polarity.

摘要： In electrostatic latent image developing process capable of effecting either positive or negative reproduction a magnetic toner of a high resistivity is controlled to form a magnetic brush having a potential insufficient for development. The toner chain constituting the brush is separated under the influence of an electric field between the developing roll and the image carrier, to produce toner particles having one polarity continuing with the developing roll, and particles of the opposite polarity transferred to the carrier.

摘要： A multi-color image formation apparatus and method of its use prevent deterioration of stability due to a recharging process in one cycle of multi-color image formation and also effectively avoid color mixing in the toner image previously formed. The multi-color image formation apparatus includes an electrostatic latent image formation member, a first electrostatic latent image formation device for forming a first electrostatic latent image on the electrostatic latent image formation member, a first developer for developing the first electrostatic latent image with a first toner, a second electrostatic latent image formation device for forming a second electrostatic latent image on the electrostatic latent image formation member, and a second developer for developing the second electrostatic latent image with a second toner. The second electrostatic latent image formation device reduces the absolute value of the potential of an image portion of the electrostatic latent image and also reduces the absolute value of the potential of the common area of background portions of the first and second electrostatic latent images.

摘要： An image recording apparatus includes an image carrying part, a developing part and an image transferring part. The image carrying part has a surface on which an electrostatic latent image is formed. The developing part develops the electrostatic image into a toner image by selectively applying toner to the surface of the image carrying part. The image transferring part transfers the toner image onto a recording sheet or an intermediate image transferring part. Fine particles are uniformly formed on the surface of the image carrying part, and a portion of the fine particles is transferred from the image carrying part with the toner image. The fine particles are smaller in diameter than the toner particles.
