Image forming apparatus and removable unit

An image forming apparatus comprising:

• an apparatus body that includes a mounting section that is provided with a first connection terminal that performs electrical connection;
• and
• a removable unit that is removably mounted on the mounting section of the apparatus body, the removable unit being provided with a second connection terminal that is disposed at a side surface portion of the removable unit and that contacts and is connected with the first connection terminal when the removable unit is mounted, the side surface portion being a side surface with respect to a movement direction of the removable unit when the removable unit is mounted or removed, wherein
• the second connection terminal is held by a holding member that is mounted on the side surface portion of the removable unit while the holding member is displaceable in a direction that is orthogonal to the 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 becomes pushed towards the outer side of the side surface portion by the elastic member that is elastically deformed in accordance with the displacement towards the inner side, so that the second connection terminal contacts the first connection terminal, and
• the side surface portion includes a mounting portion having a guiding hole formed in at least one of first and second surfaces of the mounting portion which face each other, and the holding member is provided with a fitting protrusion that is fitted into the guiding hole when the removable unit is mounted.
