PURPOSE:To always maintain correctly the quantity of a solvent adhering to transfer paper even in the case a temperature variation and a change with the lapse of time are generated by correcting automatically a driving speed of a squeeze roller in accordance with a variation of viscosity of a developer. CONSTITUTION:By detecting viscosity of a developer 21 utilized actually for development by a viscosity detecting means 52, and reflecting a variation of a result of its detection as a variation of a rotating speed of a squeeze roller 15, a variation of an actual solvent adhesion quantity caused by a variation of viscosity of the developer 21 is compensated automatically. In such a way, even in the case a variation of an ambient temperature and a change with the lapse of time of the developer are generated, the solvent adhesion quantity is always maintained correctly even if an operator does not execute a special operation for the compensation. |
