Image forming apparatus having removable fixing device

An image forming apparatus comprising:

• an image forming apparatus main body;
• an opening and closing part that is attached to the image forming apparatus main body in an openable and closeable manner;
• and
• a fixing device that is removably installed in the image forming apparatus main body to fix a developer image onto a recording medium,
• the opening and closing part being provided with an engaging portion to engage with an engaged portion defined on the image forming apparatus main body,
• wherein the engaging portion includes a pressing part that presses the fixing device toward a proper position when a part of the fixing device is positioned in a movement locus of the engaging portion during a closing movement of the opening and closing part,
• wherein one end of the fixing device in a longitudinal direction is positioned in the image forming apparatus main body through a positioning portion provided at the one end of the fixing device in the longitudinal direction, and
• wherein the pressing part is disposed at another end of the fixing device in the longitudinal direction.

• the opening and closing part being provided with an engaging portion to engage with an engaged portion defined on the image forming apparatus main body, the engaging portion being movable in an orthogonal direction with respect to an opening/closing direction of the opening and closing part,
• the image forming apparatus main body being provided with a protrusion,
• during a closing movement of the opening and closing part, the engaging portion coming in contact with the protrusion and being moved in the orthogonal direction, and
• after the engaging portion is moved in the orthogonal direction, the engaging portion pressing the fixing device toward a proper position when at least a part of the fixing device is positioned in a movement locus of the opening and closing part along the opening/closing direction.
