    摘要： A recording apparatus for recording information in a thermosensitive medium which has a photothermal conversion layer having a light wavelength absorption property and a coloring layer colored by the heat generated by the photothermal conversion layer comprises a first light source that emits a light beam for writing information to a scanning position in a main scanning direction in the thermosensitive medium, and a second light source that emits a light of lower energy density than the light beam emitted by the first light source to the scanning position in the main scanning direction in the thermosensitive medium or to the vicinity thereof. The first light source and the second light source emit lights having wavelengths within the range of the absorption property of the photothermal conversion layer respectively to form recording dots of one line in the main scanning direction in a noncontact manner with the thermosensitive medium.

    摘要： The optical unit forms an electrostatic latent image by applying scanning light onto the photosensitive member charged by the charger device from above at an angle. The developing device forms a toner image by developing the electrostatic latent image formed on the photosensitive member with toner. The transfer charger device transfers the toner image formed on the photosensitive member onto a transfer charger sheet. The main body accommodates the sheet feeding section at a rear section, and the optical unit in front of the feeding section, both of which are vertically arranged. The photosensitive member and the developing device are integrated into the image formation unit, which is detachably set in the main body. The toner box of the developing unit has a rear surface portion shaped to correspond to the optical unit, and a front surface portion shaped to correspond to an optical path through which the scanning light output from the optical unit is applied onto the photosensitive surface of the electrostatic latent image carrier.
