摘要： An image forming apparatus includes a first photosensitive member and a second photosensitive member that form images having different colors, a transfer belt that transfers the images formed on the first photosensitive member and the second photosensitive member onto a recording sheet, a first motor that rotatingly drives the first photosensitive member and the transfer belt, and a second motor that rotatingly drives the second photosensitive member. After the startup process of the first and second motors has been completed, the rotation speed of the second motor is controlled while maintaining the rotation speed of the first motor unchanged so that the second rotation phase of the second photosensitive member rotatingly driven by the second motor is the same as the first rotation phase of the first photosensitive member rotatingly driven by the first motor.

摘要： A magnetic material detecting device, in which a concentration of magnetic material can be correctly detected, even when the magnetic material with unevenness in its density distribution flows. A magnetic field generating device is arranged in a two-component developer composed of magnetic carrier and non-magnetic toner and generates a magnetic field. A signal output device is arranged in the developer and outputs a signal depending on a magnetic permeability of the developer due to the magnetic field generated by the magnetic field generating device. An agitating unit agitates the developer and makes the developer flow between the magnetic field generating device and the signal output device. A detecting unit detects a proportion of the toner in the developer based on a result of multiple times sampling of the signal outputted from the signal output device after the agitating unit starts to operate.

摘要： An image forming apparatus comprises an image carrier, a developing unit, a supply unit and a control unit. A developing unit visualizes an electrostatic latent image formed on a surface of the image carrier, using a developing material. A supply unit supplies a periodic wave as a developing bias to the developing unit. A single period of the periodic wave is formed by a first time period and a second time period. In the first time period a voltage in which a DC voltage and an AC voltage are superimposed is applied. In the second time period only a DC voltage is applied. A control unit changes the duration of the second time period according to the amount of electrostatic latent images that have been formed in succession.

摘要： An image having a quality superior to that of the prior art is obtained even if there are multiple causes of image degradation. In a color image forming apparatus that includes a plurality of rotating bodies for forming a color image by rotating in cooperation, amounts of fluctuation in the rotational speeds of the rotating bodies that cause a decline in the image quality of the color image are detected for every rotating body (i.e., for every cause) and the detected amounts of fluctuation are corrected appropriately.
