Image forming apparatus

An image forming apparatus comprising:

• a main assembly;
• an open/close portion configure to take an open state in which the open/close portion is open relative to the main assembly and a closed state in which the open/close portion is closed relative to the main assembly, the open/close portion shifting from one state of the open state and the closed state to the other state by rotating relative to the main assembly due to its own weight;
• a moving portion coupled with the open/close portion and configured to move relative to both the main assembly and the open/close portion with rotation of the open/close portion;
• a damper configured to generate a braking force for braking the open/close portion by moving with movement of the moving portion;
• a first transmitting portion coupled with the damper and configured to transmit the braking force;
• and
• a second transmitting portion to which the braking force is transmitted from the first transmitting portion by being in contact with the first transmitting portion and configured to transmit the braking force to the open/close portion,
• wherein the moving portion is provided with one of the first transmitting portion and the second transmitting portion,
• wherein the open/close portion is provided with the other one of the first transmitting portion and the second transmitting portion, and
• wherein when the open/close portion is shifted from the one state to the other state, the braking force transmitted from the first transmitting portion to the second transmitting portion is changed by changing a positional relationship between the first transmitting portion and the second transmitting portion with the movement of the moving portion.
