Abstract
In a color recording apparatus, charges are applied to a latent electrostatic image carrier by a scorotron having a grid after development of a first latent electrostatic image on the carrier with a first color toner. Thereafter, a second electrostatic latent image is formed and developed with a second color toner. If the charges given by the scorotron have the same polarity as a charging polarity of the first color toner, a potential of the grid is set to be equal to a non-image portion potential of the first latent electrostatic image, or set to have a polarity opposite to that of an image portion potential of the first latent electrostatic image assuming that the non-image portion potential is regarded as 0 V as a reference potential. If the charges given by the scorotron have a polarity opposite to the charging polarity of the first color toner, a potential of the grid is set to have a polarity opposite to that of the non-image portion potential image assuming that the image portion potential is regarded as 0 V as a reference potential.
