An image forming apparatus includes a transfer unit for which, when inclined, leakage of a liquid developer can be suppressed. The transfer unit includes an intermediary transfer belt onto which the liquid developer is transferred and which rotates. A supporting unit is capable of holding the transfer unit at a first position. A rotation holding portion is capable of holding the transfer unit at a second position inclined from the first position relative to the supporting unit. A cleaning roller is capable of removing the liquid developer on the intermediary transfer belt. A cleaning container is supported by the supporting unit irrespective of rotation of the transfer unit and is capable of collecting the liquid developer removed by the cleaning roller.
