Abstract: An image forming apparatus includes: a first member configured to have a projecting section having a reference plane parallel to a projecting direction thereof; a second member configured to have a hole into which the projecting section is inserted, an aligning section that comes into contact with the reference plane of the projecting section inserted into the hole, and a deformation section that comes into contact with, in a state bent to the inserting direction side, a surface on an opposite side to the reference plane of the projecting section inserted into the hole.

Abstract: There is provided a transfer belt unit mounting/dismounting device constituted by a decreased number of component parts capable of using the guide rails not only to guide the insertion of the transfer belt unit, but also to set the transfer belt unit to a transfer position and to return it to a non-transfer section.

Abstract: A sheet separation unit comprises a separation/conveyance roller, a separation member to be brought into contact with the roller so as to separate paper sheets drawn by the roller, an elastic member configured to bring the separation member into pressure contact with the roller, and a pair of elastic holding members that apply axial forces to respective opposite end sections of the separation member from the outside. The axial forces press the opposite end sections toward a central portion of the separation member, and the elastic holding members press and hold the separation member in a state in which the separation member can swing to and away from the roller.

Abstract: The invention provides an original reading apparatus which is small in overall thickness, light in weight and easy to hold by hand. The original reading apparatus includes a body case in the form of a flattened casing in which a power source and an electric controlling section to which power is supplied from the power source are contained. The body case has an original insertion opening formed in a wall thereof, and an original passageway is formed in the body case and communicated with the original insertion opening. An original reading section is disposed in the original passageway, and an operating section is mounted on the body case such that an operating face thereof is disposed on a surface of the body case. The original reading section and the operating section are disposed in a juxtaposed relationship in a horizontal position at a substantially same height.
