Abstract: An image forming apparatus includes a main body, a cartridge support member configured to have a process cartridge provided with first electrical contact points attachable thereto, and a holder configured to have second electrical contact points which are electrically contactable to the first electrical contact points. When the cartridge support member is moved from a first position to a second position in the main body, the second electrical contact points are electrically connected to the first electrical contact points while the cartridge support member is at the first position, while the cartridge support member moves between the first position and the second position, and while the cartridge support member is at the second position. The holder electrically disconnects the second electrical contact points from the first electrical contact points when the cartridge support member is moved to a third position outside the main body.
