摘要： An image forming apparatus includes a photosensitive member and a developer carrying member spaced from the photosensitive member by a gap. The developer carrying member carries a developer containing an externally added strontium titanate. A bias voltage is applied between the photosensitive member and the developer carrying member with a substantially rectangular waveform. This bias voltage forms an oscillating electric field therebetween. The electric field provided by the difference between a jump peak voltage of the bias voltage and the potential of the photosensitive member at a portion exposed to the light is not less than 4.1 V/micron. The electric field provided by a difference between the jump peak voltage and a potential of the photosensitive member at a portion not exposed to light is not more than 3.5 V/micron. The electric field provided by a difference between a returning peak voltage of the bias voltage and a potential of the photosensitive member at a portion not exposed to light is not more than 2.9 V/micron. A ratio of a portion of the voltage for the direction toward the photosensitive member is 20 to 50%.

摘要： Whereas a high masking effect can be secured in a space to which a masking sound is emitted, the degree of a discomfort a person existing in the space suffers can be reduced. In superimposition processing, a CPU 21 extracts sound signals in different intervals of a sound signal X12-n of a human voice, superimposes the extracted sound signals on each other on the time axis, and outputs a resulting superimposed sound signal X13-n. In shift and addition processing, the CPU 12 interchanges a sound signal, before a reference position, of a sound signal X16-n and a sound signal, after the reference position, of the sound signal X16-n (shift processing) and outputs a sound signal X17-n obtained by adding together a shift-processed sound signal X16′-n and the original, non-shift-processed sound signal X16-n.
