Developing device provided with developing roller and supply roller

摘要

In a developing device, a developing agent member has a first rotational shaft extending in a first direction. A supply member has a second rotational shaft extending in the first direction, contacts the developing agent member. A housing accommodates a developer, and includes a first wall and a second wall opposed with each other in the first direction. The first wall is formed with a first opening. The second wall is formed with a second opening. When projected in the first direction, at least the second rotational shaft is disposed in the first through-hole. When projected in the first direction, the first rotational shaft and the second rotational shaft is disposed in the first opening. When projected in the first direction, the first rotational shaft and the second rotational shaft is disposed in the second opening.

主权项

1. A developing device comprising:
a developing agent member having a first rotational shaft extending in a first direction and configured to carry developer; a supply member having: a main body extending in the first direction; and a second rotational shaft extending in the first direction, the main body contacting the developing agent member, and configured to supply the developer to the developing agent member, the main body covering the second rotational shaft and having an adhering region in which the main body is adhesively fixed to the second rotational shaft, a length of the adhering region in the first direction being shorter than a length of the main body in the first direction; and a housing accommodating the developer, and comprising a first wall and a second wall opposed with each other in the first direction, the first wall being formed with a first opening and a second opening, the second wall being formed with a third opening and a fourth opening; and a first bridge portion separating the first opening and the second opening in the first wall; and a second bridge portion separating the third opening and the fourth opening in the second wall, wherein when projected in the first direction, the first rotational shaft is disposed in the first opening and the second rotational shaft is disposed in the second opening, and wherein when projected in the first direction, the first rotational shaft is disposed in the third opening and the second rotational shaft is disposed in the fourth opening.
