Abstract
An image forming apparatus with a casing latching and opening feature includes an openable and closable member forming a part of a casing of the image forming apparatus. When the openable and closable member is closed in opposition to the biasing force of the biasing device for biasing the openable and closable member in a direction in which it is open and the biasing force of a latching or locking device, the relation W.sub.1MAX-W.sub.1L <W.sub.2MAX is satisfied when the biasing forces of the biasing device and the locking device immediately before the openable and closable member is locked by the locking device are denoted as W.sub.1L and W.sub.2MAX, respectively, and the biasing force of the biasing device at a lock position at which the openable and closable member runs beyond the lock position to be unable to move is denoted as W.sub.1MAX. Thus, the openable and closable member can be closed with ease.
