29a may be used to form an image on the photosensitive drum 21a.

Furthermore, in the embodiment shown in FIG. 1, a heat fixing method is used in the fixing section, but it is also possible to use a pressure fixing method or a heat pressure fixing method.

This makes it possible to reduce power consumption and shorten warming-up time.

In addition, in the embodiment described above, the image is formed on the photosensitive drum 21a and transferred to the belt member l; however,
As shown in FIG. 8, a method may be adopted in which image information is directly recorded on the recording medium.In other words, the same parts as in the previous embodiment are given the same reference numerals. The electrostatic recording means 22c is applied to the uniformly charged belt member l.
A latent image is formed, developed in the developing section 26c, and then fixed in the fixing section 9. The configuration and operation of the other parts are the same as those of the previous embodiment, so the explanation thereof will be omitted.

(Effects of the Invention) In the present invention having the above-described configuration and operation, even when enlarging and recording a vertically long original on an apparatus whose horizontal direction is long, it is possible to image by using a part of the divided recording means. Since information is recorded and displayed, image information can be recorded and displayed without waste.

In addition, since the recording means is isolated from the recording medium when not recording, image information from other documents, etc. can be reproduced on the recording medium without spilling image information already displayed on the display screen.
