A processing method which thermally develops a thermally developable photosensitive material which is exposed imagewise, comprising the step of thermally developing said thermally developable photosensitive material using heating element which intermittently heats and has duration time of surface temperature of not less than 250 C. This liquid crystalline polyester resin composition has excellent mechanical properties and provides an insulator which is hardly charged. Further, when the plasma arc torch is in a high frequency start mode, the start cartridge spaces the tip from the electrode such that a pilot arc is established between the electrode and the tip. Thereby providing an anti-theft function. In the electrophoretic display device, a distribution state of the electrophoretic particles is changed to effect display, and the first electrode has an area substantially equal to or larger than an area of the second electrode. In some embodiments, the detector can downscale the image data while the object detection is performed and use the downscaled image data to continue the detection process.
