摘要： A drawing system according to an embodiment of the present disclosure includes a light source section and a scanning section. The light source section generates a plurality of laser light beams having wavelengths that are different from each other and each correspond to an absorption wavelength of a photothermal conversion agent included in a recording medium. The scanning section scans a surface of the recording medium with the plurality of laser light beams in a state in which irradiation spots of the plurality of laser light beams are arranged side by side at predetermined intervals in a direction orthogonal to or obliquely intersecting with a scanning direction of the plurality of laser light beams.

摘要： An image forming apparatus includes a print head and a control circuit. The print head includes a plurality of light emitting elements arranged in a main scanning direction and a plurality of drive circuits corresponding to the light emitting elements, respectively. The control circuit is configured to add footer null image data after original image data corresponding to an image portion to be formed by one of the light emitting elements. The control circuit is configured to supply the original image data followed by the footer null image data to the print head, and cause the one of the light emitting elements to emit light in accordance with the original image data and then to be turned off in accordance with the footer null image data.

摘要： A light scanning apparatus (100) includes a light source (1), a deflector (5) configured to deflect a light flux (103) from the light source (1), and an imaging optical system configured to guide the light flux (103) deflected at the deflector (5) onto a scanned surface (7). The imaging optical system consists of a single imaging optical element (6), wherein, on the optical axis of the imaging optical system, the conditions 0.15 ‰¤ T2/Sk ‰¤ 0.3 and 0.03 ‰¤ d/K ‰¤ 0.08 are satisfied. A condition 0.3 ‰¤ B ‰¤ 0.6 is satisfied at a condensing position Y where a scanning angle ¸ is greatest, when the condensing position Y in the main scanning direction on the scanned surface (7) of the light flux (103) deflected at the scanning angle ¸ by the deflector (5) is expressed by Y = (K/B) × tan(B × ¸).
