摘要： An image forming apparatus including a conveyance unit to convey a transfer medium, a first image forming unit to form a monochrome image transferred at a first transfer position onto the transfer medium, and a second image forming unit disposed downstream from the first image forming unit in a direction of conveyance of the transfer medium, including an intermediate transfer body to form a multi-colored toner image on the intermediate transfer body. The multi-colored toner image is transferred onto the transfer medium at a second transfer position. The conveyance unit is separated from the intermediate transfer body at the second transfer position in a monochrome mode to form the monochrome image using only the first image forming unit, and contacts the intermediate transfer body at the second transfer position in a full-color mode to form a full-color image using both the first and second image forming units.

摘要： By using a black-image forming device, an abrasive pattern is formed on a sheet conveying belt so that toner is input to a contact section where a cleaning blade is in contact with the sheet conveying belt. After the toner is input to the contact section where the cleaning blade is in contact with the sheet conveying belt and then the sheet conveying belt makes one or more revolutions, a process control is performed in which Y, M, and C toner patterns and B toner pattern are transferred onto the sheet conveying belt.
