Abstract:
An image forming device for forming an image in accordance with an inputted resolution by irradiating a recording material, the image forming device comprising:a rotary drum including a peripheral surface, the rotary drum rotating in a main scanning direction in a state in which the recording material is wound onto the peripheral surface; a recording head disposed at a portion facing the peripheral surface of the rotary drum, the recording head being moveable in an axial direction of the rotary drum, which is a sub-scanning direction, the recording head being capable of irradiating with a plurality of light beams which are separated by predetermined intervals in the sub-scanning direction, and the recording head irradiating the recording material with the light beams on the basis of image data while the rotary drum is rotating; and an image data-shifting section which shifts image data, wherein the recording material is wound onto the rotary drum in an incline manner such that, in a case of recording at a predetermined resolution, a main scanning line to be recorded is parallel to an end portion of the recording material which is along a direction of winding onto the rotary drum, and in a case of recording at the inputted resolution other than the predetermined resolution, the image data-shifting section, at each occurrence of displacement of a main scanning line being recorded at the recording material, relative to a main scanning line recorded at the predetermined resolution, by a predetermined pixel amount determined in advance, shifts image data by the predetermined pixel amount in a direction opposite to the direction of the displacement.
