Patent ID: 8059978

Claim:
An image forming apparatus comprising: a first image carrier that carries an image; a first charging section that electrically charges the first image carrier; a first exposure section that forms a latent image on the first image carrier electrically charged by the first charging section; a first development section that develops the latent image formed by the first exposure section on the first image carrier by means of a first liquid developer; a first primary transfer section that transfers a first image developed by the first development section onto a transfer belt; a second image carrier that carries an image; a second charging section that electrically charges the second image carrier; a second exposure section that forms a latent image on the second image carrier electrically charged by the second charging section; a second development section that develops the latent image formed by the second exposure section on the second image carrier by means of a second color liquid developer; a second primary transfer section that transfers a second image developed by the second development section onto the transfer belt; the transfer belt which is wound around a driving roller and tension roller; a secondary transfer section that transfers the first image and the second image transferred onto the transfer belt further onto a recording medium; a media type memory section that stores a type of recording medium to be transferred by the secondary transfer section; a variable transfer pressure application mechanism that applies transfer pressure of a first level or of a second level at the secondary transfer section; a variable transfer pressure application section control section that controls the variable transfer pressure application mechanism to apply transfer pressure of the first level or of the second level according to the type of recording medium stored in the media type memory section; and a controller that corrects an amount of color shift when the transfer pressure at the secondary transfer section changes from the transfer pressure of the first level to the transfer pressure of the second level according to the type of recording medium stored in the media type memory section by the variable transfer pressure application section control section.
