Abstract:
1. An image forming apparatus comprising: a main body; a process cartridge being detachably mounted to the main body along a mounting direction perpendicular to a rotational axis direction which is a direction of a rotation axis of a photosensitive member, the process cartridge including, an exposure device configured to expose the photosensitive member in a state wherein which the process cartridge is mounted to the main body, the exposure device including, wherein the charger is arranged to be adjacent to the photosensitive member at a downstream side with respect to the mounting direction of the process cartridge, wherein the exposure device is positioned on a first line, which intersects with the rotation axis and is perpendicular to the mounting direction when seen from the rotational axis direction, in the state wherein the process cartridge is mounted to the main body, wherein the charger is positioned at an opposite side of the exposure device with respect to a second line which is parallel with the mounting direction and passes the facing part when seen from the rotational axis direction, wherein the main body includes a pressing member that presses the process cartridge toward the interval keeping members at a position at which the photosensitive member and the exposure head face each other, wherein the interval keeping members contact with the process cartridge by the process cartridge being pressed by the pressing member, wherein the exposure device is positioned and fixed to the main body in an upper-lower direction; wherein the main body includes a first guide part extending in the mounting direction and a second guide part extending in a direction perpendicular to the mounting direction, wherein the first guide part is configured to guide the process cartridge along the mounting direction, wherein the second guide part extends in the direction perpendicular to the mounting direction from an end portion of the first guide part at the downstream side in the mounting direction, wherein the pressing member presses the process cartridge in the direction perpendicular to the mounting direction such that the process cartridge is guided through the second guide part, wherein each interval keeping member includes a contact part that contacts the photosensitive member, in the state where the process cartridge is mounted to the main body, wherein the process cartridge includes a frame that supports the photosensitive member, wherein the frame includes a charger support part that supports the charger, wherein the charger support part has an upper surface, which is a surface at the opposite side of the exposure device and is substantially parallel to the second line, wherein the upper surface is positioned lower than the contact part of the interval keeping member, in the state where the process cartridge is mounted to the main body, and wherein the mounting direction is parallel to the second line.
