Abstract
An image forming apparatus has a speed range showing image forming capability per unit time that is determined in advance, and is settable to either a model set at a relatively low-speed range or a model set at a relatively high-speed range. Then, the arrangement of the laser elements is differentiated between a low-speed machine and a high-speed machine each other. Even when timing of writing for the high-speed machine is applied to the arrangement of the laser elements for the low-speed machine to write in an image, the image is not able to be written successfully, and resulting in an image which is displaced vertically.
Claims12
An image forming apparatus comprising a plurality of laser elements and a scanning optical system which scans a photoreceptor by a laser beam emitted from the laser elements wherein
- the image forming apparatus has a speed range showing image forming capability per unit time that is determined in advance, and is settable to either a model set at a relatively low-speed range or a model set at a relatively high-speed range, and
- arrangement of the laser elements of the low-speed model and arrangement of the laser elements of the high-speed model are differentiated from each other.
