Abstract
An image forming system includes an image forming apparatus including an AC-DC converter and a main board, and a sub board having a sub connector connectable with a main connector of the main board. When the sub board is not connected with the main board, a main DC-DC converter on the main board converts a DC voltage from the AC-DC converter into a first DC voltage and output the first DC voltage to a circuit element for image formation. When the sub board is connected with the main board, the AC-DC converter outputs the DC voltage to a sub DC-DC converter on the sub board via the main connector and the sub connector, and the sub DC-DC converter converts the DC voltage from the AC-DC converter into a second DC voltage and output the second DC voltage to the circuit element via the sub connector and the main connector.
