    • A electronic printing apparatus includes memory for storing a digitized image. A receiver is transported to an image forming position, the receiver including field-driven particles in a matrix that can change reflective density in response to an applied electric field. The apparatus further includes an array of electrodes for selectively applying electric fields at the image forming position across the receiver; a heater for heating the receiver to increase the temperature of the matrix so as to increase the mobility of the field-driven particles in the matrix; and electronic control circuitry coupled to the array for selectively applying voltages to the array so that fields are applied at the image forming position to the heated field-driven particles at particular locations on the receiver corresponding to pixels in response to the stored image whereby the electrode produces an image in the receiver corresponding to the stored image in the receiver.
    • 电子打印装置包括用于存储数字化图像的存储器。 接收器被传送到图像形成位置,接收器包括可以响应于施加的电场改变反射密度的矩阵中的场驱动粒子。 该装置还包括用于选择性地在接收器的图像形成位置施加电场的电极阵列; 加热器,用于加热接收器以增加基体的温度,以增加场驱动颗粒在基质中的迁移率; 以及耦合到所述阵列的电子控制电路,用于选择性地向所述阵列施加电压,使得响应于所存储的图像,将对应于像素的所述接收器上的特定位置处的所述图像形成位置处的场施加到所述加热的场驱动粒子上,由此所述电极 在接收机中产生对应于存储的图像的接收器中的图像。
