An image forming apparatus includes a first casing, a second casing, a fixing member and an adjusting member. The second casing is connected to the first casing such that the first casing and the second casing are arranged along a first direction orthogonal to a vertical direction. The fixing member connects the first casing and the second casing at a first height position in the vertical direction. The adjusting member connects the first casing and the second casing at a second height position in the vertical direction different from the first height position such that a distance between the first casing and the second casing is adjustable. The first casing and the second casing are fixed to each other with the distance adjusted to a predetermined distance by at least the fixing member and the adjusting member.

A device and a method establish an electrical connection between an electrical traction energy storage system and a high-voltage on-board electrical system for a motor vehicle. The device includes a housing, and a battery junction box assembly connected or connectable to the housing using a first detachable connection. The battery junction box assembly includes a switching device and a touch protection cover. The switching device is arranged on a carrier plate and selectively establishes or disconnects an electrical connection between a first terminal for connecting the electrical traction energy storage system and a second terminal for connecting the high-voltage on-board electrical system. The touch protection cover is configured as a cover for the switching device and is connected or may be connected to the carrier plate using a second detachable connection. The second detachable connection is arranged such that it is not accessible in an assembled state of the device.
