A developing roller (not visible in the drawings) is rotatably supported on the developing frame 20, and the developing roller can supply the developer carried on the surface thereof to the photosensitive drum.

A chip card seat 12 is arranged at one end of the photosensitive frame 10 connected with the first edge cover member 31, and the chip card seat 12 is used for mounting a chip (not shown in the figure); the chip card holder 12 and the photosensitive frame 10 are preferably integrally formed, and may also be fixedly connected. The chip-socket 12 includes two lateral position-limiting portions 121 oppositely arranged in the second direction Y, and a side of the chip-socket 12 facing the first edge cover member 31 has an opening portion 120, and a chip can be inserted into the chip-socket 12 from the opening portion 120 along the mounting direction L. As shown in fig. 2, the first direction X, the second direction Y and the third direction Z are perpendicular to each other.
