    摘要： An exposure device includes a plurality of light-emitting elements, a lighting driver, a first storage, a reader, a shading correction unit and a second storage. The lighting driver drives and lights up the light-emitting elements based on image data. The first storage stores light amount unevenness correction values of the respective light-emitting elements. The reader reads the light amount unevenness correction values stored in the first storage. The shading correction unit executes shading correction for the light amount unevenness correction values read by the reader. The second storage stores correction values obtained by having the shading correction unit to execute the shading correction for the light amount unevenness correction values. The lighting driver controls light power of the respective light-emitting elements based on the correction values stored in the second storage.

    摘要： An exposure device includes an exposure section and first and second signal output units. The exposure section has plural light emitting elements. The first signal output unit outputs to the exposure section a first signal for determining timings for starting and ending light emission of the respective light emitting elements. The second signal output unit outputs to the exposure section a second signal for determining as to whether the respective light emitting elements are caused to emit light for respective pixels. If light mission of the respective light emitting elements is stopped with respect to all pixels of one line in a main scanning direction, the first signal does not output to the exposure section for each group of one or plural light emitting elements that operate based on the common first signal.

    摘要： An image-forming device which is equipped with an image-holding member, an exposure section provided with plural light-emitting portions arranged in a first direction, a movement section that relatively moves the exposure section and the image-holding member in a second direction that intersects with the first direction, and a light-emission control section. The light-emission control section causes the plural light-emitting portions to periodically emit light in accordance with image data representing an image that is to be formed on the image-holding member, to form the image on the image-holding member. The light-emission control section varies a light-emission period during formation of the image, so as to correct for periodic fluctuations within the image of at least one of density and magnification ratio in the second direction.
