Abstract
An image forming apparatus having a humidity detector which is detachably attached to the main apparatus body that accommodates an image forming member. The humidity detector detects a humidity in the vicinity of the image forming member, converts the detected humidity into a relative humidity and outputs it. Based on the value of the output relative humidity, image forming conditions, such as the amount of exposure, are set. The humidity detecting unit contains a time detecting unit for detecting the time for replacement.
Claims3
An image forming apparatus comprising:
- an image forming means for forming an image on an image bearing member;
- a humidity detecting unit detachably mounted to said image forming means for detecting the humidity in the vicinity of said image forming means and converting the detected humidity into a voltage value corresponding to the relative humidity;
- means for adjusting the image forming conditions of said image forming means in accordance with a relative humidity detected by said humidity detecting means;
- and
- time detecting means for detecting the time for replacement of said humidity detecting means.
The image forming apparatus of claim 2, in which the time detecting means includes a battery connected to said humidity detecting means, the time for replacement of said humidity detecting means being determined from a voltage drop across the humidity detecting means.
Dependencies are inferred from the claim text.
