Abstract
An image forming apparatus includes a first image forming portion that forms a toner image on a latent image carrier with a toner containing a flat pigment; and a second image forming portion that forms a toner image on a latent image carrier with a toner not containing the flat pigment. The toner images formed by these image forming portions are transferred to a toner image carrier or a recording medium. The average charge amount per particle of the toner containing the flat pigment is smaller than that of the toner not containing the flat pigment. A transfer width is larger than the particle diameter of the toner containing the flat pigment. A transfer current flowing between the latent image carrier of the second image forming portion and the toner image carrier or the recording medium is higher than or equal to a value required to form an electric field.
