摘要： In a recording apparatus provided with a plurality of discharging ports for discharging ink, and discharging elements for discharging ink upon application of electrical pulses, the volume of ink droplets discharged from each of the discharging ports is caused to vary due to the properties of each discharging port. This variation results in a conspicuous unevenness in recording. The present invention provides a method for making such recording unevenness due to the properties of each discharging port inconspicuous by varying the volume of ink droplets discharged from each of the plural discharging ports at random. Also, the present invention provides a technique in which the volume of discharging ink droplets is varied at random by use of a specific ink in order to make the recording unevenness inconspicuous.

摘要： A copying apparatus or the like having means for scanning the original to form a line image continuously on a photosensitive member, thereby forming an entire image of the original. A photosensor is provided to scanningly detect the density of the original at each phantom segment of the original. Each segment of the original is reproduced under an image forming condition determined on the basis of the density of the segment of the original detected by the photosensor so that the original is reproduced under the image forming condition which is proper for each of the segments. The image forming condition for one of the end segments with respect to the direction of the scanning operation, however, is not determined on the basis of the existing or detected density, but is predetermined or determined independently of the existing or detected density of that segment, so as to provide a clear image at the area corresponding to the end. The similar control may be applied to the other end segment, too.
