Abstract: An image forming apparatus includes an apparatus body including a mounting section provided with a first connection terminal, and a removable unit provided with a second connection terminal. The second connection terminal is held by a holding member that is mounted on a side surface portion of the removable unit while the holding member is displaceable in a direction that is orthogonal to a movement direction of the removable unit when the removable unit is mounted or removed and while the holding member is pushed towards an outer side of the side surface portion by an elastic member. When the removable unit is mounted, the holding member becomes displaced towards an inner side of the side surface portion, and the holding member becomes pushed towards the outer side of the side surface portion by the elastic member, so that the second connection terminal contacts the first connection terminal.
