摘要： An image recording apparatus disclosed herein is capable of recording a color image with the use of a photosensitive and pressure-sensitive recording sheet. A latent image is formed on the recording sheet by exposing light emitted from an exposure light source. The latent image formed thereon is subjected to a pressure developement to provide a visible image on a color developer sheet. The visible image is then thermally fixed by a thermal fixing device which comprises a heat storing/radiating means for storing heat generated by the exposure light source and radiating the heat stored therein toward the color developer sheet. The heat storing/radiating means is disposed between the exposure light source and the developer sheet on which the visible image is formed to be in substantial contact with the color developer sheet, whereby no separate heat source is necessary for heating the color developer sheet.

摘要： A multi-beam scanner has two light emitting points ch1, ch2 and an optical system. The light emitting points ch1, ch2 are separated by a distance &Dgr;along a depth-of-focus direction. The longitudinal magnification &agr;, or the image-side numerical aperture NA, of the optical system is set so that the surface to be scanned of a photosensitive drum is positioned within a range where the depths of focus de of the light beams from the two light emitting points ch1, ch2 overlap. The multi-beam scanner can focus the light beams onto the surface of the photosensitive drum at all the scanning positions even when the optical system has curvature of field.
