    • The invention provides a developing device, a process cartridge and an image forming apparatus that allow preventing abrupt variations in toner charge on a developing roller, caused by intrusion, into a nip, of toner accumulated above a regulating member of the developing device. A developing device using a one-component developer includes: a supply roller to which one-component developer is replenished, by natural motion, from a developer storing section. The bottom of the developing device is of a size that allows the supply roller to rotate. The developing device further comprises a filling member for filling a space above the regulating member, in order to prevent the toner located above the regulating member from intruding into a nip formed between the supply roller and a developing roller.
    • 本发明提供了一种显影装置,处理盒和图像形成装置,其能够防止由显影装置的调节构件上积累的调色剂中的侵入引起的显影辊上的调色剂电荷突然变化。 使用单组分显影剂的显影装置包括:从显影剂储存部分通过自然运动补充单组分显影剂的供应辊。 显影装置的底部具有允许供应辊旋转的尺寸。 显影装置还包括用于填充调节构件上方的空间的填充构件,以便防止位于调节构件上方的调色剂侵入形成在供给辊和显影辊之间的辊隙中。
