An image forming apparatus includes: an apparatus body; an opening and closing member; a connection member having a first engagement portion that is engaged with the apparatus body and a second engagement portion that is engaged with the opening and closing member; a pressing member having a third engagement portion that is engaged with the connection member, a pressing portion that is capable of pressing the pressed portion of the opening and closing member, and an urged portion; an urging member urging the urged portion such that the pressing portion is pressed against the pressed portion. The second engagement portion is movable between a first position and a second position. When the opening and closing member is between a closed position and an open position, the pressing portion moves relative to the pressed portion while pressing the pressed portion, in conjunction with rotation of the opening and closing member.

An image forming apparatus includes an apparatus main body having a receiving portion on a conveying path, an open/close unit movable between open and close positions, a roller located on the conveying path when the open/close unit is closed, a pressure applying unit applying pressure to the roller, and a separation unit movable between first and second positions. When at the first position, the roller contacts the receiving portion with pressure from the pressure applying unit. When at the second position, the roller is separated from the receiving portion. A switching device switches the separation unit's position, controlled by a control unit. An open/close detecting unit detects the open/close unit's state. If the separation unit is at the second position and the open/close unit is detected at the open position, the control unit controls the switching device to move the separation unit to the first position.

Disclosed is an image forming apparatus including: a door configured to open a conveying path between a transfer portion for forming a toner image on a recording material and a fixing portion for fixing the toner image, the door facing a surface of the recording material traveling through the conveying path; a duct provided on the door, the duct having an intake inlet and an exhaust outlet; a fan provided inside the duct, which generates the air flow travelling from the intake inlet to the exhaust outlet; and a filter provided detachably attachable to the duct, which collects particles with a predetermined particle diameter, wherein the filter has a width that is equal to or greater than an image width of a recording material with a maximum width passing through a fixing nip portion in a widthwise direction perpendicular to a conveying direction of the recording material.
