摘要： A developing device includes a rotatable toner bearing roller and a regulation blade. The toner bearing roller has regularly-arranged projecting sections and non-projecting sections, bears toner whose volume average particle diameter is smaller than a depth of the non-projecting section relative to the projecting section, and develops a latent image borne on an image bearing member with the toner borne on the toner bearing roller. The regulation blade is for regulating an amount of the toner borne on the toner bearing roller, and abuts, with a predetermined width, against a circumferential surface of the toner bearing roller in a circumferential direction thereof in such a manner that a longitudinal direction of the regulation blade is along a direction of a rotation axis of the toner bearing roller. A tip edge of the regulation blade in a lateral direction and a thickness direction thereof is located within an abutting section having the predetermined width. The predetermined width is larger than a maximum width, in the circumferential direction, of the non-projecting section.

摘要： A test pattern P3 longer than a length Ld corresponding to a circumferential length of a developing roller is formed along a moving direction of a photosensitive member (or developing roller). The developing roller transports a great quantity of toner on its surface in a first revolution thereof and hence, the test pattern has a high density. When the residual toner runs low, the toner transport quantity is decreased in the subsequent revolution, so that the test pattern P3 is decreased in the density at its portion beyond the length Ld from its head. If a density difference is observed at place corresponding to a boundary between image portions formed in the first revolution and the second revolution, it is concluded that image quality is degraded due to the shortage of residual toner.
摘要翻译： 沿着感光构件（或显影辊）的移动方向形成长于对应于显影辊的圆周长度的长度Ld的测试图案P3。 显影辊在其第一圈中在其表面上输送大量调色剂，因此测试图案具有高密度。 当残留调色剂运行低时，调色剂输送量在随后的旋转中减小，使得测试图案P3在其头部的长度Ld以上的部分处的密度降低。 如果在与第一旋转形成的图像部分和第二旋转之间的边界对应的位置处观察到浓度差，则得出结论，由于残留调色剂的不足，图像质量下降。

摘要： Disclosed is a carrier of a developer, which is characterized in that the current value observed when a direct current is applied under a voltage of 200 V is 0.8 to 2.0 .mu.A and the relaxation time is in the range of from 4.0 to 6.0 milliseconds, that is, the characteristic values in the dynamic state, for example, in a developing apparatus, are kept with certain ranges. If this developer carrier is used, an image having a high quality can be obtained without occurrence of troubles often caused in conventional developers, such as carrier dragging (transfer of the carrier to a photosensitive material together with the toner), fogging (transfer of the toner to the background of a copying sheet) and letter thinning.
