    • An image forming apparatus comprises an exposure light source, an image bearing member and a printer head interposed therebetween. The printer head has a micro-shutter array which comprises a plurality of micro-shutters arranged in a matrix comprising a plurality of rows and a plurality of columns. Each micro-shutter comprises a first electrode connected to a terminal of a thin film transistor, a second electrode forming a common electrode and a liquid crystal interposed therebetween. On the first electrode is further provided an opposing conductor film through an insulating film, whereby a charge storage capacitor is formed. Because of the charge storage capacitor, an effective voltage applied across the liquid crystal is kept at a high level, whereby an optical signal with good contrast is given to the image bearing member even when the printer head is driven according to a high degree of time-division scheme.
    • 图像形成装置包括曝光光源,图像承载部件和插入其间的打印头。 打印头具有微快门阵列,其包括布置成包括多行和多列的矩阵的多个微快门。 每个微快门包括连接到薄膜晶体管的端子的第一电极,形成公共电极的第二电极和介于其间的液晶。 在第一电极上还通过绝缘膜设置相对的导体膜,由此形成电荷存储电容器。 由于电荷存储电容器,所以施加在液晶两端的有效电压保持在高电平,由此即使当打印头被高度地驱动时,图像承载部件也具有良好对比度的光学信号 细分方案。
