Image reading apparatus with a function for correcting nonuniformity in recording density |
摘要 |
An image recording apparatus includes a recording head in which a plurality of recording elements are arranged so as to form an image on a recording medium, a device for causing the recording head to print a predetermined test pattern, an image density reading device for reading the density of the test pattern formed by the recording head, an uneven image density correction device for correcting conditions for driving the plurality of recording elements in accordance with the result of reading, so as to make even the density of the image, a recording stabilizing device for stabilizing a recording operation performed by the recording head, and a control device for operating the recording stabilizing device before the test pattern is printed and operating the test pattern printing device after the recording head has been stabilized by the recording stabilizing device.
