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.

In a semiconductor memory device having a plurality of memory cell arrays, data input/output terminals receive information data and operations command data and also output information data read out from the memory cell arrays. An operation command buffer temporarily stores the operation command data. In response to a control signal, an operation block controls the information data to be written into the memory cell arrays and read therefrom in a manner determined by the operation command data supplied from the operation command buffer.

A semiconductor integrated circuit device comprising an internal reset circuit generating one shot pulse for resetting an internal circuit upon a power on. In the internal reset circuit, inputted to a two-input NOR gate are an output potential of an inverter inverting a first node coupled to a power supply through a capacitor, and an internal clock signal which level inverts at a predetermined timing after rising to a "H" level upon the power on. Then, the output of the NOR gate is applied to a second node in an internal circuit to be reset. The internal reset circuit outputs one shot pulses synchronizing with the first fall of the internal clock signal after the power on irrespective of a potential change rate of the first node after the power on. The first node is set to more easily attain a "H" level than the second node to be reset to a "L" level at the power on by adjusting characteristics of circuit elements connected to the first node and those of circuit elements connected to the second node. As a result, the second node is set to be without fail at a "L" level requiring no resetting when the inverted potential of the first node has a value allowing a generation of one shot pulses at the NOR gate, thereby preventing malfunction of the internal circuit due to erroneous resetting.

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.
