ABSTRACT:
A serial printer has a plurality of printing assemblies each comprising, a transport mechanism for transporting a recording sheet in a sheet transport direction, a process part, including an image bearing member with a rotary shaft which extends in a direction parallel to the sheet transport direction, for forming a latent image on the image bearing member by charging the image bearing member and developing the latent image into a developed image, a fixing unit, including a first fixing member, for fixing the developed image on the image bearing member onto the recording sheet by the first fixing member, at least one printing carriage movable in a carriage moving direction perpendicular to the sheet transport direction and supporting the process part and the fixing unit, and a transfer unit for transferring the developed image formed on the image bearing member onto the recording sheet that is interposed between the transfer unit and the printing carriage. The image bearing member rotates in synchronism with a moving speed of the printing carriage. A moving mechanism moves the printing carriage in the carriage moving direction. The printing assemblies are arranged at predetermined intervals in the sheet transport direction. A controller controls the transport mechanism so that the recording sheet is transported by predetermined amounts in the sheet transport direction.
