Abstract: A force sensor module according to an embodiment of the present disclosure includes a plurality of force sensors. Each of the force sensor includes a plurality of sensor sections having force detection directions different from each other, and a flexible rubber member that is provided to cover the plurality of sensor sections. The rubber member is configured to transmit a force inputted from outside to the plurality of force sensors by deformation corresponding to the force.

Abstract: A multicolor electrophotography apparatus for forming a color image on a rotatable photosensitive device shaped cylindrically and arranged to hold on its circumferential surface an electrostatic image optically formed by an exposing device. The apparatus includes a plurality of developing devices movably provided along the circumference of the photosensitive device for developing a plurality of different-color toner images overlapping each other. Each of the developing devices is selectively driven to take a developing position and a non-developing position, each of the developing devices being closed to photosensitive devices up to the developing position and being separated therefrom up to the non-developing position. When the exposing device is in the non-operated state, at least one of the developing devices takes the developing position and the other developing devices take the non-developing positions.

Abstract: A developing device for developing a latent electrostatic image for an electrophotographic copying machine includes a cylindrical resilient body such as a fur brush or a roller of sponge for triboelectrically uniformly charging a single component developer of the dry type supplied from a developer storage casing and for coating the developer as a uniform thin layer on a developer carrier such as a developing roller.
