Developing cartridge and process cartridge

摘要

A developing cartridge includes a developing roller with a shaft, a housing with a wall portion, a developing electrode, a first contact portion, a second contact portion, and a connecting portion. The developing electrode includes a first contact portion contacting the shaft and has a first surface against which an apparatus electrode of an image forming apparatus body slides, a second contact portion disposed next to the first contact portion, and a second surface configured to contact an electrode of the image forming apparatus. The connecting portion includes a first inclined surface connecting the first surface and the second surface with each other and being contiguous with the first surface. The first inclined surface is inclined toward the second contact portion from the first contact portion such that the first inclined surface extends in a direction away from the wall portion.

主权项

1. A developing cartridge for use in an image forming apparatus with an apparatus electrode, the developing cartridge comprising:
a developing roller having a rotational shaft that extends in a first direction; a housing having a wall portion and configured to store a developing agent therein; and a developing electrode configured to be electrically connected to the developing roller, the developing electrode including:
a first contact portion contacting the rotational shaft and having a first surface that is positioned to slide against the apparatus electrode;a second contact portion disposed next to the first contact portion and having a second surface configured to contact the apparatus electrode; anda connecting portion including a first inclined surface connecting the first surface and the second surface with each other and being contiguous with the first surface, the first inclined surface inclined toward the second contact portion from the first contact portion such that the first inclined surface extends in a direction away from the wall portion.
