ABSTRACT:
A conveying unit conveys a recording sheet in a sheet conveying direction. A carriage includes a processing unit including an image carrier which is rotated about a rotational axis parallel to the sheet conveying direction. The processing unit forms a latent image on the image carrier by electrically charging and developing the latent image so as to produce a developed image. A transfer unit transfers the developed image on the image carrier to the recording sheet as a result of inserting the recording paper between the image carrier and said transfer unit as the carriage moves on the recording sheet in a carriage moving direction. A fixing unit fixes the developed image onto the recording sheet, and a supporting member rotatably supports the processing unit and the fixing unit. A moving unit moves the carriage in the carriage moving direction which is perpendicular to the sheet conveying direction. A retreating mechanism rotates the processing unit and the fixing unit so as to remove the image carrier and the fixing unit from the transfer unit.
