ABSTRACT:
This invention relates to an electrophotographic device in which a latent image is formed on a recording drum by toner material. The invention prevents unused toner from being attached to the recording drum so that the quality of an image formed can be improved. In this invention, a carriage is conveyed in a perpendicular direction to a feeding direction of recording paper for printing thereon. A developing roller of a developing device mounted in a process portion is wider than an effective imaging area of the recording drum and is narrower than a charged area thereof. Also, sealing members can be provided at both end surfaces of the developing roller.
