Abstract:
1. An image forming apparatus comprising: an opening and closing member configured to rotate with respect to an apparatus main body to open an inside of the apparatus main body; a first engaging portion and a second engaging portion provided in the apparatus main body; a first engaged portion and a second engaged portion provided in the opening and closing member and configured to engage with the first engaging portion and the second engaging portion of the apparatus main body, respectively; and an urging unit configured to urge the opening and closing member in a direction opposite to a direction to close the opening and closing member, wherein the first engaged portion is arranged one side of the opening and closing member in a direction of a rotation shaft of the opening and closing member, and the second engaged portion is arranged the other side of the opening and closing member in a direction of a rotation shaft of the opening and closing member, and when the first engaging portion and the first engaged portion engage with each other and the second engaging portion and the second engaged portion engage with each other, the opening and closing member is held in a closed state, wherein, when the opening and closing member is being closed, urging force which the one side of the opening and closing member receives from the urging unit is larger than the urging force which the other side of the opening and closing member receives from the urging unit, wherein, when the opening and closing member is closed from an opened state of the opening and closing member, the first engaged portion engages the first engaging portion by moving through the first engaging portion and the second engaged portion engages the second engaging portion by moving through the second engaging portion, and wherein a distance which the first engaged portion moves until the first engaged portion engages with the first engaging portion is shorter than a distance which the second engaged portion moves until the second engaged portion engages with the second engaging portion while the first engaged portion and the second engaged portion are caused to engage with the first engaging portion and the second engaging portion, respectively, by closing the opening and closing member from the opened state.
