Abstract
(EN)
A heating device (9) includes a heater (22), a holder (23), a device frame (40), a primary positioner (A), a secondary positioner (B), and a tertiary positioner (C). The heater includes a heat generator (60). The holder holds the heater. The device frame is configured to support the holder. The primary positioner is configured to position the heater and the holder in a longitudinal direction of the heater. The secondary positioner is configured to position the holder and the device frame in the longitudinal direction of the heater. The tertiary positioner is configured to position the device frame and a body of an image forming apparatus in the longitudinal direction of the heater. The primary positioner and one of the secondary positioner and the tertiary positioner are disposed on an identical side defined by a center of the heat generator in the longitudinal direction of the heater.

La présente invention concerne un dispositif de chauffage (9) qui comprend un élément chauffant (22), un support (23), un cadre de dispositif (40), un positionneur primaire (A), un positionneur secondaire (B) et un positionneur tertiaire (C). Le dispositif de chauffage comprend un générateur de chaleur (60). Le support maintient le dispositif de chauffage. Le cadre de dispositif est configuré de manière à supporter le support. Le positionneur primaire est configuré de manière à positionner le dispositif de chauffage et le support dans une direction longitudinale du dispositif de chauffage. Le positionneur secondaire est configuré de manière à positionner le support et le cadre de dispositif dans la direction longitudinale du dispositif de chauffage. Le positionneur tertiaire est configuré de manière à positionner le cadre de dispositif et un corps d'un appareil de formation d'image dans la direction longitudinale du dispositif de chauffage. Le positionneur primaire et l'un ou l'autre du positionneur secondaire et du positionneur tertiaire sont disposés sur un même côté défini par un centre du générateur de chaleur dans la direction longitudinale du dispositif de chauffage.
