发明名称 Image recording apparatus having density correction of plural recording elements
摘要 An image recording apparatus for recording an image by using a plurality of recording elements which are driven an accordance with an image signal includes a first correction unit for correcting driving conditions of the recording element, and a second correction unit for correcting a level of the image signal, wherein a variation in the recording elements is corrected by a combination of the first and second correction units. A driving voltage or a width of drive pulse which is applied to each recording element is controlled as a driving condition, thereby making uniform an uneven image density.
