Abstract
An image forming apparatus comprises an image forming paper supply section for supplying image forming paper having a paper base, an image forming section for forming a given image on the image forming paper supplied from the image forming paper supply section, an enclosure for enclosing at least the image forming paper supply section, and a cooling/dehumidifying unit for cooling the inside of the enclosure and condensing and aqueous components contained in the air inside the enclosure, thereby to dehumidify the inside of the enclosure.
Claims10
An image forming apparatus comprising:
- an image forming paper supply section for supplying image forming paper having a paper base;
- an image forming section for forming a given image on said image forming paper supplied from said image forming paper supply section;
- an enclosure fully enclosing at least said image forming paper supply section except for a paper exhaust opening of the image forming section to keep air from entering said enclosure;
- and
- cooling/dehumidifying means for cooling the inside of said enclosure and condensing aqueous components contained in the air inside said enclosure, to thereby dehumidify the inside of said enclosure.
In a image forming apparatus having a recording paper roll, a recording head, a developer, and an exhaust roller for forming, on an electrostatic recording sheet, an electrostatic latent image by said recording head and for forming a toner image by said developer, and for exhausting the recording sheet with a toner image formed thereon by said exhaust roller, the improvement comprising:
- an enclosing chamber substantially fully enclosing a recording paper roll, a recording head, a developer, an exhaust roller, and a sheet convey path extending between the recording paper roll and the exhaust roller to keep air from entering said enclosing chamber, and a cooling, dew condensation type dehumidifying device provided in the enclosing chamber.
In an image forming apparatus having a recording sheet supply roll, a recording sheet takeup roll, and a color image forming section arranged therebetween, and also having a mechanism for reciprocating the recording sheet between the supply and takeup rolls for each color image formation, the improvement comprising:
- an enclosure for enclosing a recording sheet convey path extending between the supply and takeup rolls through the color image forming section, and a cooling/dehumidifying means provided to condense aqueous components in the air inside the enclosure into due, thereby dehumidifying the air inside the enclosure.
