In an air conditioner equipped with an air cleaner, a front panel is provided with three air inlets: a first air inlet located on the front face of the front panel, a second air inlet located on the top face thereof, and a third air inlet located therebetween. Each of the first and second air inlets has an opening/closing unit including louvers, and an air cleaner is arranged on the inside of the third air inlet. At the time of cooling/heating operation and at the time of dehumidifying operation, the first and second air inlets are opened and closed by the opening/closing unit, by which the amount of air passing through the air cleaner is changed, thereby utilizing the air cleaner effectively.

An image forming apparatus includes a movable image bearing member; an image forming device for forming a toner image on the image bearing member; a charging member for charging the image bearing member in a charging station; and an electrical power source for supplying power to the charging member. A detector detects the voltage-current characteristic between the charging member and the image bearing member; and a controller controls the output of the electrical power source, in accordance with an output of the detector, when a surface area portion of the image bearing member, where the toner image is not going to be formed as the image bearing member rotates, is in the charging station.

Image forming apparatus including control means for controlling an

An image forming apparatus includes a movable image bearing member, having a photosensitive layer; an image forming device for forming an image on the image bearing member: a charging member for charging the image bearing member; and a light radiating device for radiating light on the image bearing member; a detector for detecting a datum rotating to a thickness of the photosensitive layer on the basis of the voltage-current characteristic between the charging member and image bearing member; and a controller for controlling the amount of light radiated from the light radiating device to be increased with decrease in the thickness of the photosensitive layer, in response to the detector.

Image forming apparatus having charging member

The present invention provides an image forming apparatus with an image forming device for forming a developer image on a recording material, an applicator for applying developer to form an image on an image bearing member to form a developer bearing area. A length of the developer bearing area in the generatrix direction of the image bearing member is longer than a maximum image width on the image bearing member in the generatrix direction thereof.

Image forming apparatus having contact member capable of contacting with

A charging device includes a member to be charged, and a charging member for charging the member to be charged. The charging member includes a surface layer which can contact the surface of the member to be charged. A voltage is applied between the member to be charged and the charging member. The contact angle with water .gamma..sub.R of the surface layer of the charging member is greater than the contact angle with water .gamma..sub.D of the surface of the member to be charged. An image forming apparatus includes the above-described charging device.
