Abstract: An inkjet printing apparatus adopting short pulse heating is designed to output a uniform image without unevenness. To this end, in a serial inkjet printing apparatus, a print head is subjected to a short pulse heating treatment before each print scan is carried out. In a case where a print medium is a first print medium, the print head is heated to a first target temperature before carrying out each of the print scans. In a case where the print medium is a second print medium, the print head is heated to a second target temperature lower than the first target temperature before carrying out each of the print scans.

Abstract: Images with high image quality having less time-difference unevenness are outputted in an inkjet printing apparatus that performs multi-pass printing using full-line inkjet print heads 2. For this purpose, a CPU is capable of setting a first printing method in which an image for a unit area is printed by a specified number of printing conveyance operations and a second printing method in which an image for a unit area is printed by a smaller number than the specified number of printing conveyance operations. The CPU sets conveyance conditions such that a taken time for one printing conveyance operation of the printing conveyance operations for a unit area in the second printing method is smaller than a taken time for one successive printing conveyance operation of the printing conveyance operations for a unit area in the first printing method.

Abstract: A wiping device includes a cleaning member and a control unit. The cleaning member performs wiping operation to wipe an ejection port surface of a recording head. The recording head includes the ejection port surface on which an ejection port, for ejecting ink containing particles of a coloring material, is formed. The control unit controls the cleaning member to perform the wiping operation in a state where particles are imparted to a surface of the cleaning member. The imparted particles are different in type from the coloring material particles and each imparted particle has a particle diameter greater than a diameter of each of the coloring material particles.
