    摘要： An image forming apparatus comprises: an image forming unit to form an image onto a recording medium; a measuring unit to measure a density of the image formed on the recording medium; a controller to execute an image stabilizing control to decide image forming conditions of the image forming unit on the basis of the image density measured by the measuring unit; a heater to heat a load by supplying a current to the image forming apparatus; and a detector to detect a temperature of the load which is heated by the heater, wherein the controller controls the execution of the image stabilizing control in accordance with an output of the detector at the start of the power supply to the apparatus. When the detected temperature of the load is less than a predetermined value, the image stabilizing control is executed. When it is equal to or higher than the predetermined value, the image stabilizing control is not performed. When the image stabilizing control is executed, the control means allows the image forming unit to form a sample image and the image forming conditions are controlled on the basis of the state of the sample image.

    摘要： One or more scans used to apply a specific ink are varied according to the overlapping conditions of the specific ink and a non-specific ink, and bias in the specific ink nozzle usage frequency and bias in the printing ratio among passes is suppressed. For this purpose, one or more scans used to apply the specific ink are determined on the basis of applying amount information for the specific ink and the non-specific ink. For example, the one or more scans used to apply the specific ink are determined such that the ratio of specific ink applied by the last half of plural scans is greater for a unit pixel whose application ratio of non-specific ink to specific ink is greater than a predetermined ratio than for a unit pixel whose application ratio of non-specific ink to the specific ink is less than the predetermined ratio.

    摘要： The present invention provides an ink jet printing apparatus, an ink jet printing method, a data generation apparatus, a computer program, and an ink jet printing system by which a timing for ejecting a processing liquid can be changed to improve image performance of a printed image such as abrasion resistance, to provide the printing head with a longer life, and to improve a throughput. The processing liquid is ejected to a predetermined area on a printing medium, for which a formation of an image by ink is completed, in two or more scannings among five scannings of the printing head. When an amount of ejection data for ejecting the processing liquid in the fifth scanning for ejecting only the processing liquid is equal to or lower than a predetermined amount, the fifth scanning is not carried out.
