摘要： For a serial color ink jet printing apparatus that forms an image using a symmetric printing head that ejects large dots and small dots, the configuration of a printing head is provided for suppressing, to the extent possible, a cyclic fluctuation in the main scanning direction. According to the present invention, individual nozzle arrays are arranged so that two nozzle arrays, i.e., a cyan nozzle array c1 and a magenta nozzle array m1, that are located nearer each other, form dots on adjacent scan lines. With this arrangement, a high quality image, having neither an uneven density nor an uneven color, can be formed when a printing head is inclined, or when a cyclic shift in printing positions occurs, depending on the position of the main scanning direction.

摘要： In a printing apparatus improvement of drying ability and reduction of consumed power are concurrently achieved by improving the efficiency of drying ink. More concretely, hot air is blown onto a print medium printed by ink, and a portion of the blown hot air is recovered and blown again. Before the hot air is blown, the print medium is heated by a preheating unit, making it higher than the dew point temperature of the blown hot air.

摘要： An applying amount to an applying medium is controlled in a liquid applying apparatus. Specifically, before driving a pump, a circulation speed decision processing (S3) is carried out. According to this decided speed, a speed of the circulation flow generated in a liquid holding space is controlled in a pump operating process (S4). This controls a pressure in the liquid holding space. As a result, a state of flow of the applying liquid at a contact member of a liquid holding member in contact with the applying roller is changed, and an amount of the applying liquid adhering to an applying roller and going out of the contact portion is controlled. This can control the amount of the applying liquid to be applied to the applying medium.

摘要： A liquid applying apparatus can prevent an applying liquid from evaporating while an applying operation is stopped and can reliably prevent the liquid from leaking even when, for example, the posture of the apparatus is tilted. An abutting member of a holding member is abutted, under an urging force of a spring, against an applying surface of an applying roller. Thus, a liquid holding space is formed between the applying roller and a holding member to hold the applying liquid. The abutting member is annularly formed of a single member. The applying roller rotates to cause the applying liquid held in the holding space to adhere to an outer peripheral surface of the applying roller. The applying liquid is then applied to the applying medium.
