A sheet manufacturing apparatus， the control method of a sheet manufacturing apparatus， and a sheet

Provided are an apparatus for producing a sheet， which is capable of effectively utilizing a plurality of supply units， and the like. This apparatus for producing a sheet comprises: a defibrating unit that defibrates a starting material， which contains fibers， in the air; a mixing unit which mixes an additive and the defibrated product obtained by the defibrating unit in the air; a plurality of supply units for supplying the additive to the mixing unit， each of which has a container part where the additive is contained and supplies the additive contained in the container part to the mixing unit; a forming unit which forms a sheet by depositing a mixture obtained by the mixing unit and applying heat and pressure to the mixture; and a control unit which performs a first supply action of selecting one supply unit from among the supply units having the container parts where an additive of the same kind is contained and supplying the additive to the mixing unit.
