The average shape factor SF1 of the toner is from 125 to 135, the number of particles having shape factor SF1 of less than 125 is from 5% to 30% by number with respect to the total number of toner particles, the number of particles having shape factor SF1 of greater than 135 is from 5% to 30% by number with respect to the total number of toner particles, the scratch line width in a scratch strength test of the resin used in the resin-coated layer is from 80 μm to 200 μm, and the scratch depth is from 60 μm to 150 μm.
摘要:
A rotating operation type electronic component has a rotation shaft and a signal generating section. The rotation shaft has a rod-shaped intermediate section, a cylindrical operation section, and a coupling section coupling the upper end of the intermediate section with the operation section. The rotatable operation section covers the upper part of the intermediate section, and is mounted with an operation knob. The signal generating section generates an electric signal in response to the rotation of the operation section. The coupling section has strength at which it breaks when a load of a predetermined level or higher is applied to the operation section from an axial direction of the rotation shaft.
