摘要： An image forming apparatus includes an image support which supports an electrostatic latent image on a surface of the image support. A developing unit has a developing agent support which retains a developing agent, including a toner and carriers, contained in the developing unit. The developing unit converts the latent image on the image support into a toner image by causing the toner to adhere to the surface of the image support. A developing bias supplying unit supplies a developing bias voltage to the developing agent support of the developing unit, the developing bias voltage being one of a DC bias voltage and an AC bias voltage. A timer measures a non-driven period of the developing agent in the developing unit. A control unit selects one of the DC bias voltage and the AC bias voltage from the developing bias supplying unit based on the non-driven period measured by the timer, and controls the developing bias voltage at an output of the developing bias supplying unit such that the selected one of the DC bias voltage and the AC bias voltage is supplied to the developing agent support.

摘要： An image recording apparatus for electrostatically forming a latent image on an image carrier by driving optics in response to multi-level image data. Before the start of an actual image recording operation, a latent image in the form of a test pattern having a plurality of tones is formed on the image carrier by pulse width modulation.
