    • An image forming apparatus writes an image to a display recording medium at a write position. The image forming apparatus includes an insertion slot, a transport unit, an image light emitting device and a separating/contacting unit. The display recording medium is inserted into the insertion slot. The transport unit transports the display recording medium inserted, to/from the write position. The image light emitting device includes an emitting surface that emits two-dimensional image light for irradiating a photoconductive layer of the display recording medium at the write position. The separating/contacting unit brings the emitting surface separate from a display recording medium surface when the display recording medium is not opposed to the image light emitting device, while the transport unit transports the display recording medium. The separating/contacting unit brings the emitting surface into proximity to the display recording medium surface when the display recording medium is at the write position.
    • 图像形成装置在写入位置将图像写入显示记录介质。 图像形成装置包括插槽,传送单元,图像发光装置和分离/接触单元。 显示记录介质插入到插槽中。 传送单元将显示记录介质传送到/从写入位置插入。 图像发光器件包括发射二维图像光的发射表面,用于在写入位置照射显示记录介质的光电导层。 当显示记录介质不与图像发光装置相对时,分离/接触单元将发射表面与显示记录介质表面分离,同时传送单元传送显示记录介质。 当显示记录介质处于写入位置时,分离/接触单元使发射表面接近显示记录介质表面。
