PURPOSE:To execute printing of high quality by suppressing an outflow of a carrier of a printing part, by setting a magnetic force of a carrier of a developer used for a developing process to >=2,000 Gauss (at2KOe). CONSTITUTION:A latent image formation, and a development by a two- component developer using a carrier whose particle size is 5-30mum are executed repeatedly on one or plural photosensitive bodies 46, and toner images of different colors are formed on the photosensitive body 46, and by transferring them in a lump to recording paper 40, multicolor recording is executed. In this case, as the two-component developer, a developer in which the saturation magnetic flux density of a carrier is >=2,000 Gauss (at2KOe) is used. In such a way, an outflow of the carrier of a printing part can be suppressed, a color mixture is prevented, and a natural color reproduction of a color toner can be executed.
