Claims
- 1. A serial electrophotographic apparatus comprising:
- transporting means for transporting recording paper;
- a carriage equipped, at least, with processing means for exposing an image carrying body rotated about an axis parallel to a direction in which said recording paper is transported, forming a latent image by exposing a charged image carrying body, and developing said latent image to produce a visible image;
- transferring means, provided in a position such that said recording paper is led through a space between said carriage and said transferring means, for transferring said visible image onto said recording paper as said carriage is being translated;
- translating means for translating said carriage above said transferring means, in a direction perpendicular to said direction in which said recording paper is transported;
- fixing means for fixing said visible image transferred onto said recording means by a heated fixing member;
- a heating means for heating said fixing means; and
