Portable electrophotographic printer of reduced height

Claim 1

An electrophotographic printer comprising an image-forming unit comprising a cylindrical, electrostatic latent image-bearing member, an electrostatic latent image-forming means, a developing means disposed near said electrostatic latent image-bearing member and equipped with a magnet roll for a magnetic developer containing magnetic toner, a transfer means disposed near said electrostatic latent image-bearing member for transferring the developed image on the surface of said electrostatic latent image-bearing member onto a recording medium, a cleaning means disposed near said electrostatic latent image-bearing member for cleaning the surface of said electrostatic latent image-bearing member after transferring of said developed image, and a fixing means disposed downstream of said electrostatic latent image-bearing member for heat-fixing said developed image onto said recording medium, wherein an outer diameter of said electrostatic latent image-bearing member is 40 mm or less, an outer diameter of said magnet roll is 30 mm or less, and a height of said image-forming unit is 60 mm or less, and wherein a process speed equal to a peripheral speed of said image-bearing member and a fixing speed is 60 mm/sec or less.
