<p><P>PROBLEM TO BE SOLVED: To provide an image forming apparatus in which image quality can be enhanced by suppressing unevenness in the density of an image. <P>SOLUTION: An LED array control section 34 performing driving control of an LED print head 7 comprises a section 35 for storing characteristics data consisting of the light quantity data of individual LED elements constituting an LED array 31, data concerning to a beam and resolution data, a driving current correction data operating section 39, an image signal processing section 42, a control signal generating section 43, and an image data correction operating section 44. The driving current correction data operating section 39 reads out the characteristics data stored in the characteristics data storing section 35 and calculates driving current correction data P according to an operational expression. The image data correction operating section 44 corrects image data outputted from the image signal processing section 42 using the driving current correction data P outputted from the driving current correction data operating section 39. Corrected image data is outputted to the LED print head 7. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
