    摘要： An image forming apparatus (100) includes a latent image carrier (2) to carry a latent image, a developing device (5) to develop the latent image with toner to form a toner image on the latent image carrier (2), a transfer unit (6) to transfer the toner image onto a recording medium, and a controller (30). The controller (30) executes an image density adjustment control of adjusting a developing bias to obtain a target image density, and further executes a forced toner consumption control of forcibly consuming the toner contained in the developing device (5) by attaching the toner to the latent image carrier (2) to form a toner pattern on the surface of the latent image carrier (2). The controller (30) executes the forced toner consumption control to forcibly consume a smaller amount of toner in response to a higher developing bias as adjusted by the image density adjustment control.

    摘要： An apparatus for developing a latent image on a latent image carrier (7,8) includes a toner carrier (1,3) and multiple electrodes (21,22,23,24) arranged at intervals (P) on a surface of the toner carrier. A potential difference is formed between even-numbered electrodes (22,24,...) and odd-numbered electrodes (21,23,...) of the electrodes by applying a first pulse voltage to the even-numbered electrodes and a second pulse voltage to the odd-numbered electrodes so that toner on the surface of the toner carrier moves back and forth between the electrodes, where the first and second pulse voltages are in different phases, in particular of opposite phase, and the toner moving back and forth between the electrodes is conveyed to a position facing the latent image carrier by movement of the surface of the toner carrier and thereby caused to adhere to the latent image on the latent image carrier.
