摘要：
A developing device (4) which can stably supply a developer to a latent image carrier (1) by preventing scattered developer from being discharged and thereby preventing the developer from being discharged undeterred that the amount of developer within the developing device does not increase, and an image forming apparatus using the developing device. A block member (3) serving as a scattered developer discharge prevention member is provided so as to block a path through which the developer scattered as a result of a conveyance operation of a supply screw (8) serving as a developer conveying member moves toward a developer discharge port (94). Accordingly, the scattered developer is prevented from reaching the developer discharge port and being discharged therefrom.
摘要（中）：
一种显影装置（4），其可以通过防止散射的显影剂被排出并且从而防止显影剂的排出而使显影剂稳定地供应到潜像载体（1），使得显影装置内的显影剂的量不增加;以及 使用该显影装置的图像形成装置。 设置用作散开的显影剂排出部件的块部件（3），以阻挡作为用作显影剂传送部件的供给螺杆（8）的输送动作而散发的显影剂的路径朝向 显影剂排出口（94）。 因此，防止散开的显影剂到达显影剂排出口并从中排出。
