FIG. 1 is a sectional view showing an embodiment of an electrophotographic developing device according to the present invention. In Fig. 1, A is an example of immediately after installing the brush-setting defect erasing member 5, B is an example where the member 5 has lost its elasticity due to creep deformation and the ability to form a developer pool has been reduced due to insufficient pressing force, and C is an example of creep deformation. An example is shown in which the member 5 is installed upside down, has sufficient pressing force, and forms a sufficient developer reservoir. Also, D to F are A to C, respectively.
This is an example of the cross-sectional shape of the member 5 in the case of . FIG. 2 is a diagram illustrating poor ear standing due to the blocking material 10. In the figure, 1 is a developing roll, 3 is a doctor plate, and 5 is a brushing defect erasing member.
