Abstract: An image forming apparatus includes: first and second drum members that extend in one direction and have a cylindrical shape; first and second sheet members that are replaceably wound around outer peripheries of the first and second drum members, respectively, in a state where one end and the other end of each of the first and second sheet members are separated from each other in a circumferential direction, the first and second sheet members coming in contact with a medium on which an image is to be formed; and an angular displacement mechanism that angularly displaces the first and second drum members in tandem to switch among a first attachment position where the one end of the first sheet member is attached to the first drum member in a state where the first sheet member is removed, a second attachment position where the second sheet member is attached to the second drum member in a state where the second sheet member is removed, and a third attachment position where the other end of the first sheet membe

Abstract: A toner collection device includes a toner containing portion that is moved in one direction to be installed on a side of a main body and includes a discharge port that discharges toner in an intersecting direction that intersects with the one direction, a toner collection portion that is provided on the side of the main body and collects toner via a collection port opposed to the discharge port of the toner containing portion moved in the one direction, a seal member that is provided between the discharge port and the collection port and is compressed to increase a sealing property of a connection portion between the discharge port and the collection port and suppress scattering of the toner to outside, and a mechanism that increases a compression amount of the seal member along with movement of the toner containing portion in the one direction.

Abstract: Provided is a fuel control device for an internal combustion engine that is able to detect the correct boost voltage regardless of the temperature condition, and stabilize the boost voltage value, and is able to inject an accurate amount of fuel from a fuel injection valve. The boost voltage value detected when current is not flowing in a boosting capacitor at least during a boosting operation is taken as a legitimate boost voltage value, and this legitimate boost voltage value is compared with a prescribed boost voltage value to control the boosting operation. Thus, it is possible to stabilize the boost voltage at a legitimate boost voltage value regardless of the temperature condition, and it is possible to inject an accurate amount of fuel from a fuel injection valve, thereby improving fuel consumption.
