    • Flat field uniformity can be improved in images produced by an image development system having a development roller interposed between a supply of developer and an imaging element. A raw feed of developer is supplied from the developer supply to the development roller to produce both a metered feed of developer and an overfeed of developer, which is returned to the supply, from the raw feed. A plurality of mass densities of developer used in the system and a plurality of developer velocities through the system are determined, and respective product values of those developer mass densities and those developer velocities are thereafter calculated or otherwise determined. A maximum value of the respective product values is identified, and the image development system is then operated so that the maximum product value is produced.
    • 可以改善由具有介于显影剂供应源和成像元件之间的显影辊的图像显影系统产生的图像中的平坦场均匀性。 显影剂的原料从显影剂供应供应到显影辊,以从原料中产生显影剂的计量饲料和返回到供应源的显影剂的过量进料。 确定在系统中使用的多个显影剂质量密度和通过该系统的多个显影剂速度,然后计算或以其他方式确定那些显影剂质量密度和那些显影剂速度的相应乘积值。 识别相应产品值的最大值,然后操作图像显影系统,从而产生最大产品值。
