    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.

    摘要: An image forming apparatus includes: a latent image forming unit scanning and exposing an image carrier according to image data, to form a latent image; a transfer body on which a toner image is transferred and a reference index for setting an output start time point of the image data is formed; a detecting unit facing the reference index and outputting a detection signal changing in accordance with passing of the reference index; and a controller controlling the output start time point with the detection signal. The controller starts a first period during which change of the detection signal is ignored, according to first change of the detection signal, starts a second period after the first period, regards second change of the detection signal occurring first in the second period as a reference of the output start time point, and ignores change of the detection signal after the second change.

    摘要: A set value output circuit includes a first output unit and a second output unit. The first output unit outputs a signal input to a first input when a first timing signal is input to a second input, and continues to output the signal until a next first timing signal is input. The second output unit outputs the signal input to a third input when the second timing signal is input to a fourth input, and continues to output the signal until a next second timing signal is input. A selection unit inputs a selected timing signal as the second timing signal to the fourth input. A control unit inputs the first timing signal to the second input, so that a set value for an image to be formed next is output during image formation using the signal output from the second output.
