Abstract:
1. An image forming apparatus, comprising: a photosensitive element; a charging unit that charges a surface of the photosensitive element; a writing unit that forms a static latent image on the photosensitive element by irradiating the charged surface of the photosensitive element with light based on input image data; a developing unit that supplies toner to the static latent image on the photosensitive element so as to form a toner image; a transfer unit that transfers the toner image onto a recording medium; and a fixing unit that fixes the toner image to the recording medium by applying heat and pressure to the toner image, wherein the writing unit includes: the writing unit is configured to slightly change the writing clock period so as to enlarge or shrink a formed pixel in the main-scanning direction and further perform enlargement or shrinkage in the sub-scanning direction with reference to the image magnification information of the correction map, and thus cancel an image deformation caused by the deformation of the recording medium and correct a change in an image magnification in the main-scanning direction.
