Image recording apparatus capable of correcting density unevenness

Claim 1

An image recording apparatus comprising: input means for inputting image signals; recording means having a plurality of image recording elements for recording an image on a recording material by driving said plurality of image recording elements in accordance with the image signals, wherein a predetermined image recorded by said plurality of image recording elements is representative of density unevenness in accordance with a change in a temperature or a variation in a recording characteristic of said plurality of image recording elements; data generating means for generating data based on predetermined image density unevenness recorded by said recording means; temperature detection means for detecting the temperature of said recording means and outputting a temperature detection result; correction data calculation means for outputting common density unevenness correction data for correcting density unevenness in accordance with a temperature detection result output from said temperature detection means and the data based on the density unevenness output from said data generating means; and correction means for making a correction to each of the image signals input from said input means based on the common density unevenness correction data output from said correction data calculation means and outputting corrected image signals to said recording means, wherein said correction means corrects the image signals in such a manner that an image recorded at a uniform density can be produced when the image signals input from said input means to said plurality of image recording elements are at a uniform level.
