ABSTRACT:
A light weight, portable electrophotographic printer having an image-forming unit which includes a cylindrical latent image bearing member, a device for forming the latent image, a developing device equipped with a developing roll onto which is attracted a non-magnetic one-component developer or a two-component developer containing a magnetic carrier and non-magnetic or slightly magnetic toner. The printer also has a device for transferring the developed image on the surface of the latent image-bearing member onto a recording medium, a device for cleaning the surface of the latent image-bearing member after transferring the developed image, and a device including rollers located downstream of the latent image-bearing member for heat-fixing the developed image onto the recording medium. The outer diameter of the latent image-bearing member is 40 mm or less, the outer diameter of the developing roll is 30 mm or less, and the peripheral speed of the latent image-bearing member is 60 mm/sec or less, height of the image forming unit being 60 mm or less.
