Abstract:
A developing cartridge includes: a developing roller; a first frame; and a second frame. The first frame includes: a first melt-bonding surface extending in a first direction; and a second melt-bonding surface positioned closer to the developing roller than the first melt-bonding surface. The second melt-bonding surface forms an obtuse angle with the first melt-bonding surface. The second frame is melt-bonded to the first frame. The second frame includes: a first wall having a third melt-bonding surface melt-bonded to the first melt-bonding surface and extending in parallel to the first melt-bonding surface; a second wall having a fourth melt-bonding surface melt-boned to the second melt-bonding surface and extending in parallel to the second melt-bonding surface; and a protruding portion having a surface intersecting the fourth melt-bonding surface and protruding in the first direction from the second wall toward the developing roller.
