摘要： An image forming apparatus to form an image on a recording material includes a photosensitive member, an exposure device to form a latent image on the photosensitive member, a tubular body defining a space in which at least a part of the exposure device is contained, and a support portion that supports the exposure device and is provided along a rotation axis direction of the photosensitive member in the space of the tubular body. The image forming apparatus further includes, in the rotation axis direction, a first side plate fixed to one end portion of the tubular body, and a second side plate fixed to another end portion of the tubular body. One support portion end portion in the rotation axis direction is fixed to the first side plate, and another support portion end portion in the rotation axis direction is fixed to the second side plate.

摘要： An image forming apparatus including a first member having a first face, a first protrusion and a second protrusion projecting from the first face, and a groove portion formed in the first face, and a second member having a second face provided with a first hole and a second hole. The first protrusion and the second protrusion are inserted into the first hole and the second hole. The second face is superposed on the first face so that the groove portion located between the first member and the second member is in a visible state. The second face is sandwiched between a part of the first protrusion inserted in the first hole and the first face. The second hole in which the second protrusion has been inserted has a gap between the second hole and the second protrusion in an extending direction of the groove portion.

摘要： An image forming apparatus includes an image forming portion, a frame, which is a part of a main assembly frame, extending along a predetermined plane, a cover provided outside of the frame and extending along the predetermined plane and a circuit board, provided between the frame and the cover with in a direction perpendicular to the predetermined plane and extending along the predetermined plane. An opening portion penetrating the circuit board is formed in the circuit board. The frame includes a first abutting portion protruding toward the circuit board and the cover includes a second abutting portion protruding toward the circuit board. The first and second abutting portions are opposite to each other via the circuit board and positioned in an area where the opening portion of the circuit board is sandwiched therebetween in the direction perpendicular to the predetermined plane.
