Abstract: An image forming device includes a photosensitive drum, a development roller, a current detection circuit, a power supply part and a power supply control part. The development roller develops an electrostatic latent image formed on the photosensitive drum and forms a toner image on the photosensitive drum. The current detection circuit detects a development current flowing between the photosensitive drum and the development roller when the toner image is formed and outputs a detection signal showing a current value of the development current. The power supply part applies a voltage on the development roller. The power supply control part controls the power supply part such that a variation of the voltage has a negative correlation with a variation of the current value shown in the detection signal.

Abstract: A toner container attachment detecting device includes a reader-writer, a shutter made with an electrically conductive material and provided movably between an open position where the shutter is kept from influencing a carrier wave radiated from an antenna of the reader-writer and a covering position where the shutter influences the carrier wave, and first and second displacing portions. When the toner container is attached to an apparatus body, the first displacing portion displaces the shutter to the open position. When the toner container is removed from the apparatus body, the second displacing portion displaces the shutter to the covering position. A radio field intensity detecting section of the reader-writer detects a radio field intensity of the carrier wave and a determining section of the reader-writer determines, based on a detection result of the radio field intensity detecting section, whether or not the toner container is attached to the apparatus body.

Abstract: An image forming apparatus includes a photosensitive drum, a developing section, a voltage applicator, a detector, a calculating section, and an evaluating section. The detector detects values of first and second currents. The first current flows between the photosensitive drum and the developing section during formation of an electrostatic latent image. The second current flows between the photosensitive drum and the developing section when the electrostatic latent image is not being formed. The calculating section calculates a toner charge-to-mass ratio. The evaluating section evaluates reliability of a calculation result of the toner charge-to-mass ratio by comparing the second current value to a reference value. The reference value is of a reference current flowing between the photosensitive drum and the developing section when the electrostatic latent image is not being formed, and indicates a current value detected after adjustment to at least one of the photosensitive drum and the developing section.
