摘要： In a conductive board heater using metal as the board, since thermal expansion is large, and expansion and shrinkage are repeated in a heating apparatus, there is a defect that the electrode portion to which a power supply spring contact point on the power supply connecter side is pressurized and contacted is worn and contact inferior occurs and it is easy to break. Furthermore, since the position of the resistor pattern of the heating body varies, excessive heating, insufficient heating, uneven heating at an end portion, or uneven curl unevenness at a paper end is occurred. A heater in an image heating apparatus is provided so as to prevent a contact defect between an electrode and a connecter of image heating apparatus.
