摘要： A semiconductor laser is caused to emit laser light continuously on a plurality of scanning lines prior to image formation in a laser printer. An electric current to be applied is controlled so that the detected light quantity from the semiconductor laser becomes equal to the desired light quantity. The light quantity detected during pulsed emission with the applied current is used as the desired light quantity for APC which is performed at a space between sheets when a non-image area is scanned. Alternatively, laser light is emitted on a plurality of lines before the start of printing when printing of multiple pages is to be performed in a laser beam printer, to perform light quantity control. Then, laser light is emitted during scanning of a nonimage area between pages, to perform light quantity control. When light quantity control is performed between sheets, a value obtained by correcting an error between the quantities of light in both types of light quantity control is set as the desired light quantity. Alternatively, laser light is emitted continuously on a plurality of scanning lines prior to image formation to perform light quantity control. Then, laser light is emitted only when laser is scanning a non-image area to perform light quantity control, thereby setting a current volume to be applied to the semiconductor laser during image formation.

摘要翻译： 在激光打印机中形成图像之前，使半导体激光器在多条扫描线上连续地发射激光。 控制要施加的电流，使得来自半导体激光器的检测光量等于期望的光量。 在施加的电流的脉冲发射期间检测到的光量被用作在扫描非图像区域时在片材之间的空间处执行的APC的期望光量。 或者，在打印开始之前，在激光束打印机中进行多页打印时，在多行上发出激光，进行光量控制。 然后，在页之间的非图像区域的扫描期间发射激光，以进行光量控制。 当在纸张之间进行光量控制时，将通过校正两种类型的光量控制中的光量之间的误差而获得的值设定为期望的光量。 或者，在图像形成之前，激光在多条扫描线上连续发射，以进行光量控制。 然后，仅当激光扫描非图像区域才能进行光量控制时才发射激光，从而在图像形成期间设定要施加到半导体激光器的电流体积。

摘要： An electrophotographic image forming apparatus includes a first electrostatic-capacity generating portion disposed at such a position that the first electrostatic capacity generating portion contacts the developer accommodated in the developer accommodating portion. The first electrostatic capacity generates portion generating an electrostatic capacity corresponding to an amount of the developer. A second electrostatic-capacity generating portion is disposed at such a position that the second electrostatic-capacity generating portion does not contact the developer accommodated in the developer-accommodating portion. The second electrostatic capacity generating portion generates a reference electrostatic capacity. A developer amount detector is provided for detecting an amount of the developer accommodated in the developer-accommodating portion on the basis of the electrostatic capacity generated by the first electrostatic-capacity generating portion and the reference electrostatic capacity generated by the said second electrostatic-capacity generating portion.
