An image forming apparatus that forms an image according to an electrophotographic system includes plural developing units provided in a cylinder, which freely rotates a fixed angle at a time around a rotation shaft, to rotate together with the cylinder. Toner levels of toner cartridges arranged in the developing units are detected by rotating the cylinder a predetermined angle to stop the cylinder and measuring a flow-down time of a toner, which flows down inside of the toner cartridge, using an optical sensor.
摘要:
An image forming apparatus that can satisfy productivity at the time of double-sided image formation without jamming due to a collision of a succeeding sheet with a preceding sheet, and without upsizing of the apparatus. The image forming apparatus performs a sheet circulation transport for circulating and transporting a sheet to an image forming unit to perform image formation on both a first side and a second side of the sheet. The sheet is fed to the image forming unit at a predetermined image formation start timing for the first side image formation. The first side image-formed sheet is reversed, and re-fed to the image forming unit for the second side image formation while causing the first side image-formed sheet to wait at least one of sheet waiting positions. A full state where all the sheet waiting positions are full of the first side image-formed sheets is detected. The sheet feeding unit is controlled so that the number of sheets on which the sheet circulation transport is performed is greater than the number of the sheet waiting positions. When the full state detecting unit detects the full state, the sheet re-feeding unit is controlled so that a head sheet among the first side image-formed sheets waiting at the sheet waiting positions is fed in advance of the predetermined image formation start timing.

Signals outputted from oscillators (1-1, 1-2, . . . 1-n) are in phase with signals as reflected by band elimination filters (3-1, 3-2, . . . 3-n) at elimination frequencies of the band elimination filters (3-1, 3-2, . . . 3-n), while they are in opposite phase with signals leaked from the corresponding band elimination filters (3-1, 3-2, . . . 3-n). In this way, a stable oscillation can be performed with the oscillation frequencies of the oscillators (1-1, 1-2, . . . 1-n) balanced as optimum frequencies between the natural frequencies of the oscillators (1-1, 1-2 , . . . 1-n) and the elimination frequencies of the band elimination filters (3-1, 3-2, . . . 3-n), while the oscillators (1-1, 1-2, . . . 1-n) can be synchronized with the elimination frequencies being used as reference frequencies.
