Abstract: An image forming apparatus includes an image forming unit configured to perform image formation on a sheet, a casing configured to house the image forming unit, an operation unit configured to receive an operation performed by a user, an electric wire extending from the casing to be connected to the operation unit and configured to transmit an electrical signal, a reinforcing member provided separate from and independent of the electric wire, the reinforcing member interconnecting the casing and the operation unit, and a covering configured to enclose therein the electric wire and the reinforcing member, wherein the reinforcing member is fixed to the casing and the operation unit in such a manner that a distance between a portion fixed to the casing and a portion fixed to the operation unit in the reinforcing member is shorter than a total length of the electric wire.

Abstract: A fuel-efficient hydraulic fluid has a lower viscosity than a standard hydraulic fluid, a pressure loss decreases, and thus, when control based on a standard model is exercised, the speeds of various actuators increase. However, the speeds need not be increased beyond the speeds of the standard model. Instead, it is preferred that fuel efficiency be improved. As a result, an engine revolution speed decreases by 50 rpm and a pump torque decreases by 5%. This reduces an engine output. Therefore, when a hydraulic fluid is changed from the standard hydraulic fluid to the fuel-efficient hydraulic fluid, the fuel efficiency can be improved while maintaining operability equivalent to that of the standard model. Hence, the fuel efficiency can be improved while maintaining the operability when an item affecting the fuel consumption is replaced. In addition, the settings can be changed with ease by a service technician.
