摘要： After a toner image is transferred from a photoreceptor to an intermediate transfer belt, a surface of the photoreceptor is destaticized by a static eraser including a plurality of light emitting elements arranged in an axial direction of the photoreceptor. A first density sensor and a second density sensor for detecting densities of toner applied to the intermediate transfer belt are provided at a position where a large quantity of light from the static eraser is applied to the photoreceptor surface and a position where a small quantity of light from the static eraser is applied to the photoreceptor surface. In a case where a density difference between the detected toner densities exceeds a predetermined threshold value, a destaticization controller carries out an additional destaticizing operation by the static eraser.

摘要： An image forming apparatus includes a latent-image bearing body, a charging unit, a latent-image writing unit, a development unit, a development power, and a bias control unit. After a start of an image forming operation, the bias control unit performs a process of constantly maintaining an output of a development bias at an adjustment bias value. The adjustment bias value is a central value in a periodic fluctuation range of the output of the development bias. At a timing at which a difference of the development bias from the adjustment bias value in the periodic fluctuation range is less than or equal to a predetermined threshold value, the bias control unit performs switching from the process of constantly maintaining the output of the development bias at the adjustment bias value to a process of periodically changing the output of the development bias based on development bias control data.

摘要： A toner-image detecting sensor for detecting a toner image before being transferred onto a recording sheet and a fixed-image detecting sensor for detecting the toner image after being secondarily transferred and fixed on the recording sheet are arranged so that the positions of them in a main scanning corresponding direction are aligned. An image forming apparatus has a first image adjustment mode and a second image adjustment mode. In the first image adjustment mode, image adjustment is made on the basis of only a result of detection by the toner-image detecting sensor without transferring the test pattern onto the recording sheet. In the second image adjustment mode, the test pattern is transferred onto the recording sheet, and image adjustment is made on the basis of both a result of detection by the toner-image detecting sensor and a result of detection by the fixed-image detecting sensor.
