Title: Image recording apparatus

Abstract: The improved image recording apparatus that performs image recording on arecording material to output a print with a record of a visible imageincludes an outputting device of a print having printed thereon a minimumdensity in the recording material, a measurement device for measuring theminimum density that has been recorded on the print, and a control deviceby which tones to be recorded are controlled in accordance with theminimum density measured by the measurement device. The image recordingapparatus that uses various recording materials including light-sensitivematerials and thermal recording materials and which, in spite of thefluctuation in the fog density of a particular recording material or thedifference in characteristics between production lots and otheridentifications of the recording material, is capable of consistentrecording of high-quality images that assure satisfactory tonerepresentation over the entire density range including low densities.
