PURPOSE: To suppress the generation of static electricity and to prevent electrostatic fog by providing a humidifier in a housing.

CONSTITUTION: The humidifier which uses gauze 7 and water 8 is provided in the housing of a film feeder, and the amount of humidification is controlled with a slide plate 5. A film 3 from a supply magazine 1 is fed by a necessary amount by a capstan roller 10 through each guide roller 6, exposed 4 on the way, and taken up around a take-up magazine 2. In this case, the film 3 rubs against the guide rollers 6 to generate static electricity, and an electrostatic fog is caused, but the generation of static electricity is suppressed by providing the humidifier to prevent the electrostatic fog.
