    摘要: A push type switch which enables an operator to obtain an upscale impression when he operates the push type switch. A switch body 3 is rigidly fixed to a printed wiring board 5. A casing 7 having a plurality of guide grooves 71h is fixed to the printed wiring board 5. A plurality of rails 91a provided on a knob 9 capable of transmitting a pushing force to the switch body 3 are slidably inserted into the guide grooves 71h such that the knob 9 can slide on the casing 7. A grease is applied to the guide grooves 71h and the rails 91a. The viscosity of the grease is set to be within a range of 1000 to 2750 Pa.

The above objects are achieved when the toner contains a binder resin and colorant, inorganic fine particles, and a hydrotalcite compound shown by the formula: M1y12+M2y22+ . . . Mjyj2+L1x13+L2x23+ . . . Lkxk3+(OH)2.(X/n)An−.mH2O  (1) wherein 0
