    • 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.
    • 显影装置包括可旋转的调色剂承载辊和调节叶片。 调色剂承载辊具有规则布置的突出部分和非突出部分,其承载体积平均粒径小于非突出部分相对于突出部分的深度的调色剂,并且将图像显影载体 墨粉承载辊上的调色剂。 调节叶片用于调节承载在调色剂承载辊上的调色剂量,并以预定的宽度在调色剂承载辊的圆周方向上以其周向方向抵接在调色剂承载辊的圆周表面上, 调节叶片沿着调色剂承载辊的旋转轴线的方向。 调节叶片的横向方向和其厚度方向的前端位于具有预定宽度的邻接部分内。 预定宽度大于非突出部的圆周方向上的最大宽度。

    • An image forming apparatus includes: a controller and an engine. The controller includes a first memory configured to store therein first setting information for driving the image forming element. The engine includes: an image generation unit configured to drive the image forming element; a second memory configured to store therein second setting information for driving the image forming element; and an initialization processor configured to initialize the image generation unit based on the second setting information before a communication between the controller and the engine is established, to compare the first setting information with the second setting information after the communication between the controller and the engine is established, and to execute an initialization of the image generation unit based on the first setting information when the first setting information does not correspond to the second setting information.

    • An image forming apparatus includes a developer bearing member for transporting developer to an opposing position opposing an image bearing member. Regularly-disposed concave sections are formed on a surface of the developer bearing member. An alternating voltage that includes a first voltage for moving developer from the developer bearing member toward the image bearing member, and a second voltage for moving developer from the image bearing member toward the developer bearing member is applied to the developer bearing member. A cycle period of the alternating voltage is larger than a minimum width of the concave section in a circumferential direction of the developer bearing member divided by a moving velocity of a surface of the rotating developer bearing member.
    • 图像形成装置包括用于将显影剂输送到与图像承载部件相对的相对位置的显影剂承载部件。 在显影剂承载部件的表面上形成有常规设置的凹形部分。 包括用于将显影剂从显影剂承载部件朝向图像承载部件移动的第一电压和用于将显影剂从图像承载部件朝向显影剂承载部件移动的第二电压的交流电压被施加到显影剂承载部件。 交变电压的循环周期大于显影剂承载部件的圆周方向上的凹部的最小宽度除以旋转的显影剂承载部件的表面的移动速度。
