Claims

[Scope of utility model registration request]

In an image forming apparatus including a paper transport mechanism including a movable transport section and a fixed transport section each having a plurality of transport rollers and forming an openable and closable paper transport path, one end of the movable transport section is supported. It is rotatably supported by a shaft, and a lock mechanism is provided at the other end on a line passing through the center of gravity of the movable conveyance section and where the left and right weights are balanced, and the lock mechanism is locked by closing the movable conveyance section. A paper conveyance mechanism characterized in that the conveyance rollers of the respective conveyance sections are configured to come into even pressure contact with each other when the conveyance mechanism is pressed.
