Abstract

See full text

A wet type electrophotographic image forming apparatus is capable of indicating timing of replacement of filter due to influence of solvent used in the process of image formation whereby to cause degradation of image quality or fatigue of parts and to restrict discharged vapor concentration of collected solvent. The image forming apparatus employing an ink containing a solvent includes a liquefying device for cooling the solvent evaporated during an image forming process and collecting liquefied solvent, an air pump sucking vapor left unliquefied by the liquefying device and maintained in a vapor state, a pressure sensor detecting a suction pressure of the air pump, and alarm device for comparing an absolute value of a pressure data generated by the pressure sensor and indicative of the suction pressure and a predetermined pressure range and generating an alarm when the absolute value of the pressure data is output of the pressure range.
