摘要： An image forming apparatus forms a latent image on a photoconductor by irradiating light beams from a plurality of light sources onto the photoconductor. A detection unit detects a time difference between timings of start writing on the photoconductor by the light beams in a main scanning direction. A calculation unit calculates a shift of each of the light beams in a sub-scanning direction based on the time difference detected by the detection unit and a rotation speed of the photoconductor. A correction unit corrects irradiated positions on the photoconductor by the light beams in the sub-scanning direction based on the shift calculated by the calculation unit.

摘要： In an image forming device, a correction unit corrects image formation operation based on a plurality of correction patterns. A pattern creation unit forms an electrostatic latent image of the correction patterns on a photoconductor and transferring the image to an intermediate transfer body to form the correction patterns thereon. A pattern detecting unit detects the correction patterns formed on the intermediate transfer body. A speed detecting unit detects a movement speed of the correction patterns on the intermediate transfer body are moved. A timing holding unit computes a set value of detection start timing for starting detection of each correction pattern to hold the set value. The correction unit is provided to determine, in advance of correcting image formation operation, a detection start timing based on the movement speed and the set value.

摘要： An image formation apparatus for forming an image and test patterns. The image formation apparatus includes a storage unit that stores dither matrix data used to form the image and the test patterns; and an image formation unit that forms the test patterns based on the dither matrix data. A number of tones of the test patterns to be formed by the image formation unit is changed and the number of tones is determined based on a size of the dither matrix data and a number of bits per pixel within the dither matrix data.
