摘要： A toner density detecting device is provided with a coil buried in a housing and a cover member provided on one end of the coil to prevent the developing agent from touching the coil. The cover member has a front end portion provided near the surface of the housing and extending along the developing agent flowing direction and an apex portion at the back of the front end portion with respect to the direction. The apex portion projects deeper into the developing agent than the front end portion. An edge connecting the front end portion and the apex portion extends in the direction to cross the central axis of the coil. A pair of faces extending in the direction on either side of the edge are gradually declined from the edge toward the surface of the housing.

摘要： The present invention has been made to provide an image forming apparatus capable of suppressing reverse charging caused by a transfer electric field to thereby suppressing memory image level to a lower level without providing a charge eliminating unit. In am image forming apparatus according to the present invention, a controller 191 increases and decreases a transfer current from a transfer roller 23 in accordance with the rise and fall of setting values to be set of the background potential of a photoconductor drum 10 and developing bias potential of a developing unit 18. By increasing and decreasing the setting value of the transfer current as described above, it is possible to suppress memory image level (residual image level) that can be caused when the setting values of the background potential of the photoconductor drum 10 and developing bias potential are decreased. In the case where the setting values of the background potential of the photoconductor drum 10 and developing bias potential are set back, the transfer current is also set back, so that it is possible to keep the memory image level at a favorable level.

摘要： As a peeling device for peeling off a paper from a photosensitive drum after completing the transfer of an image, a peeling charger and a sucking fan are used jointly and the sucking wind velocity level of the sucking fan can be controlled by switching it with a controller. With the increase in thickness of a paper, the sucking fan is switched and controlled for reducing a wind velocity level of the sucking fan. Further, in the continuous copying, the sucking fan is switched and controlled so as to reduce a sucking wind velocity level until the peeling of the leading edge of a succeeding paper is started after peeling the leading edge of a current paper. Thus, a sucking wind velocity of the sucking fan is minimized when peeling a paper from the photosensitive drum.
