摘要： An image forming apparatus is for transferring a toner image on an image carrier onto a transfer medium, and thermally fixing the toner image by a fixing device, and comprises a cleaner removing residual toner on the image carrier. The apparatus: acquires information relating to a distribution of a density of the residual toner at each position within a section on the image carrier at an end of an image forming job, the section extending from the transfer position to immediately before a cleaning position; determines, based on the information, whether or not the density of the residual toner at the transfer position exceeds a corresponding threshold density pertaining to occurrence of fusion of the residual toner; and causes, if determining negatively, the drive unit to stop when the image forming job is completed and the residual toner at the transfer position reaches a predetermined position within the section.

摘要： An image forming apparatus having an image carrier that carries a toner image; an opposed member that is provided so as to be opposed to the image carrier; an application device that applies a bias to the opposed member; and a control device that controls the application device to apply a first bias and thereafter a second bias to the opposed member so as to remove toner from the opposed member. The first bias has an absolute value that is large enough to cause discharge from the opposed member into air. The second bias has an absolute value that is too small to cause discharge from the opposed member into the air, and has a reverse polarity to the first bias.

摘要： An image forming apparatus comprises: a rotatable image carrier operable to carry a toner image on a surface thereof; a transfer part operable to electrostatically transfer the toner image carried on the surface of the image carrier, onto a transfer material; a cleaning member that is in contact with the surface of the image carrier and that is operable to clean toner remaining on the surface of the image carrier after transfer by the transfer part; and a voltage supplier operable to apply, to the cleaning member, a bias voltage that is for cleaning the surface of the image carrier and that has a polarity opposite to a normal charging polarity of the toner. Here, application of the bias voltage by the voltage supplier starts before rotation of the image carrier starts, and when Vr>0, 0

摘要： An image forming apparatus performs an image forming operation and an untransferred toner particles transfer operation. In particular, the image forming apparatus has an image bearing member, the image bearing member having an endless image bearing surface and supported for rotation, a charging member made of a brush provided in contact with the image bearing surface to define a charging region, and a controller. The controller controls the image forming operation in which the toner image is provided to a recording medium and the transfer operation the transfer operation in which the rotation of the image bearing member is halted and then toner particles accumulated in the brush are transferred onto the image bearing surface at the charging region.
