    摘要: A developing apparatus includes a developer containing portion containing a developer having a weight average particle diameter of not more than 7 &mgr;m, a developer bearing member for bearing a developer, and an agitating member that agitates the developer contained in the developer containing portion. The agitating member is intermittently driven with respect to rotation of a developing sleeve. The agitating member is driven to rotate for one page every time the image forming apparatus performs a predetermined number of printing operations. A rod member having a crank-like shape may be used as the agitating member and both of the end portions serve as the center of rotation. By controlling the drive of the agitating member, it is possible to effectively adjust the supply of toner to the developing sleeve and prevent the density lowering phenomena caused due to inflow of a large amount of the new toner presented at the rear of the developing container. The agitating member may be positioned closest to the developing sleeve and may be arranged below the toner container. Accordingly, to these arrangements, the image density after printing a low print pattern can be prevented from being lessened to obtain a uniform image density even though a one-component magnetic developer having the weight average particle sized diameter of not more than 7 &mgr;m is used.

    摘要: A memory medium is provided to a cartridge detachably mountable to an image forming apparatus. Into the memory medium, as information for performing charge control, information on the amount of usage of an image-bearing member and information on a charging alternating voltage (a threshold value for selection control of a charging peak-to-peak voltage Vpp) are written. The image forming apparatus includes a charging-bias power-supply circuit, on its body side, including AC oscillation output circuit capable of outputting two or more species of alternating peak-to-peak voltages and an AC detector for detecting an alternating current passing through the image-bearing member. Charge control is performed on the basis of a detected value detected by the AC detector and memory information for the cartridge, whereby good charge control space saving, and cost reduction of the power-supply circuit are compatibly realized.
