摘要： A potential sensor is provided in which the adhesion of toner particles to the potential sensor is reduced or prevented from occurring, reducing or preventing the occurrence of a situation that accurate detection cannot be performed. The potential sensor has a movable member, detecting electrodes formed on the movable member, a support which movably supports the movable member, a driving mechanism which drives the movable member, and a stationary member which supports the support. Between the movable member and the stationary member, a first gap is so formed as to make the movable member 101 movable. The first gap has a part that is not larger in width than the maximum size of toner particles when the movable member is not elastically deformed and is at a neutral position.

摘要： An imaging apparatus adjusts the polarization directions of irradiation beams (to a diffraction grating) corresponding to first and second beams respectively which have different polarization directions (for example, by adjusting a relative angle formed between light-emitting ends of respective polarization maintaining fibers) so that the spectral characteristics of the irradiation beams at the diffraction grating coincide with each other. Then, the imaging apparatus acquires a tomographic image indicating polarization information for a object based on beams (that come from the diffraction grating for splitting and diffracting a beam from the adjustment unit) corresponding to the first and second beams respectively which have different polarization directions.
