摘要： A mode in which a toner image formed on an intermediate transfer belt passes through a primary transfer portion without a toner image being transferred from a photosensitive drum onto the intermediate transfer belt is provided. In the mode, an area of the photosensitive drum that passes through the primary transfer portion while the toner image is passing through the primary transfer portion is defined as a first area. When the first area passes through a charging position, a charging bias is adjusted so that the occurrence of an image defect is prevented.

摘要： In a rotary-type image forming apparatus in which detection of electrostatic capacitance is performed when a developing apparatus is in a posture less affected by a toner density within the developing apparatus, a toner in the developing apparatus, which is located at a development position during the detection of the electrostatic capacitance, is avoided from being uselessly consumed. The image forming apparatus has a remaining amount detection mode of detecting a toner remaining amount on condition that a developing roller of one developing apparatus positioned opposite to another developing apparatus, for which the toner remaining amount is to be detected, stands by in a state spaced from a drum.
