    • An ink jet image forming apparatus and a control method thereof are provided to prevent deterioration of image quality according to the nozzle deformation in the head chip of the print head. An ink jet image forming apparatus comprises plural nozzles(120,130) for spraying ink, heaters(H1,H2) which are arranged in order to regulate the ink spray angle to the respective nozzles, and a head chip(100) having a heater drive unit operating the heaters. The heater drive unit includes one or more heater switches making heater current flow in the serially connected heaters, one or more auxiliary resistances connected to the connection point of the heaters, and one or more auxiliary switches making heater current flow in the auxiliary resistances so that the current flowing in each heater changes according to the operation of the auxiliary switch and the heater switch.
    • 提供一种喷墨图像形成装置及其控制方法,以防止根据打印头的头部芯片中的喷嘴变形引起的图像质量的劣化。 喷墨图像形成装置包括用于喷射墨水的多个喷嘴(120,130),为了调节与各个喷嘴的喷墨角度而布置的加热器(H1,H2)以及具有加热器驱动单元 操作加热器。 加热器驱动单元包括一个或多个加热器开关,其使串联连接的加热器中的加热器电流流动,连接到加热器的连接点的一个或多个辅助电阻以及使加热器电流在辅助电阻中流动的一个或多个辅助开关,使得 每个加热器中流动的电流根据辅助开关和加热器开关的操作而改变。
