Abstract
An electrophotographic apparatus with an endless photosensitive member such as a photosensitive drum. The electrophotographic apparatus includes a dew condensation preventing device for preventing dew condensation on the photosensitive member, a temperature sensor for detecting a temperature in the vicinity of an outer surface of the photosensitive member, and a humidity sensor for detecting a humidity in the vicinity of the outer surface of the photosensitive member. The electrophotographic apparatus further includes a calculating unit for calculating a water vapor density having a given functional relationship with temperature and humidity, according to the temperature detected by the temperature sensor and the humidity detected by the humidity sensor, a storing unit for storing a preset control value, and a control unit for controlling the dew condensation preventing device according to the water vapor density calculated by the calculating unit.
