摘要： An image forming apparatus is provided with an exposure lamp (3) for emitting the light so as to illuminate a document; a magnification changer for increasing and reducing the magnification of a reflected light image from the document; an imaging assembly including a photosensitive member (10) and a charger (11) for charging the photosensitive member (10), and adapted for forming an image on the surface of the photosensitive member (10) based on the reflected light image passed through the magnification changer, a developing device (16) for causing charged toner to deposit on the formed image whereby to form a toner image, and a controller for controlling a light emission amount of the exposure lamp (3) so as to attain a desired toner image density. The control means includes a calculator for calculating the light emission amount according to the set magnification based on a relationship between the light emission amount and the magnification of the magnification changer so as to attain the desired toner image density, and a correcting device for correcting the calculated light emission amount based on a relationship between a factor other than the magnification which influences the toner image density. Accordingly, the light emission amount of the exposure lamp (3) can be set in accordance with various factors including the document density such that an image of the desired image density can be obtained even in an enlargement mode or a reduction mode.
摘要翻译：图像形成装置设置有用于发光的曝光灯以照射文件; 用于增加和减小来自文件的反射光图像的放大率的倍率变换器; 一种成像组件，包括用于对感光构件充电的感光构件和充电器，并且适于基于通过倍率变换器的反射光图像在感光构件的表面上形成图像; 用于使带电调色剂沉积在形成的图像上从而形成调色剂图像的显影装置; 以及用于控制曝光灯的发光量以获得期望的调色剂图像浓度的控制器。控制装置包括一个计算器，用于根据放大量与倍率变换器的倍率之间的关系根据设定的倍数来计算发光量，以获得所需的调色剂图像浓度;以及校正装置，基于影响调色剂图像浓度的倍率之外的因素与调色剂图像浓度之间的关系计算发光量。因此，曝光灯的发光量可以根据包括文件密度的各种因素来设定，使得即使在放大模式或缩小模式下也可以获得期望的图像浓度的图像。
