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： There is provided an image forming apparatus and method capable of reducing a measurement error in a measurement result of the surface potential of an electrostatic latent image formed on the surface of an image bearing member. The measurement error occurs under the influence of an electric field generated from a pre-exposed area. Consequently, miniaturization of an image forming apparatus and consistent print quality can be achieved. The image forming apparatus includes an image forming control section for determining an error correction value corresponding to the charge state of a latent image on the basis of relationships between charge states of the latent image and error correction values which have been prepared in advance, computing an error corrected potential measurement value using the error correction value and a potential measurement value, and controlling the image forming apparatus on the basis of the error corrected potential measurement value.
