Abstract: An electrophotographic image forming apparatus including an absolute humidity derivation section which derives absolute humidity inside the apparatus, and a control section which, when the absolute humidity inside the apparatus derived by the absolute humidity derivation section is smaller than a predetermined first threshold value, sets a dither pattern density based on an original image to be smaller compared to when the absolute humidity inside the apparatus is larger than the predetermined first threshold value, and forms a latent image on a photosensitive drum.

Abstract: In an image forming apparatus provided with a detachable fixing unit having fixing paired-rollers, a heating unit heats at least one of the fixing paired-rollers, and a temperature detecting unit detects a temperature of the detachable fixing unit. The image forming apparatus is further provided with an adjustment mechanism for preventing the detachable fixing unit from being taken out from the apparatus body, when the temperature detecting unit determines that the temperature of the detachable fixing unit exceeds a predetermined value, and allowing the detachable fixing unit to be taken out from the apparatus body, when the temperature detecting unit determines that the temperature of the detachable fixing unit is the predetermined value or less, whereby protecting users from getting their hands burned when taking out the detachable fixing unit from the apparatus body.
