  • Ink drier and ink jet type image forming apparatus mounting the same
    Patent number: 6406141
    Abstract: In an ink drying portion, a conveying roller and a rigid roller are rotated by driving force of a driving roller which is transmitted through a driving belt. Air in a housing is discharged by means of a fan and air is sucked into the housing through a clearance between the conveying rollers. A paper conveyed into the ink drying portion is continuously held along a paper drying passageway by the air sucking effect of the discharge of the fan and is consecutively conveyed along the paper drying passageway through the conveying roller. An ink on the paper is dried by direct irradiation with infrared rays from an infrared heat source or by indirect irradiation with infrared rays reflected by a reflecting plate.
