发明名称 IMAGE FORMING APPARATUS AND IMAGE QUALITY MAINTAINING METHOD
摘要 A technique is provided that enables maintaining an appropriate level of image quality even under conditions that the quantity of residual toner increases in an image forming apparatus in which a lubricant is supplied to a cleaning target part from which a residual toner is removed by a cleaning member. In timing when a toner image carried on an image carrier reaches a predetermined transfer position, reaching failure information indicating that a sheet to which the toner image should be transferred does not reach the predetermined transfer position is acquired. In the case where the reaching failure information is acquired, an electric field that is opposite to an electric field generated when transferring the toner image on the image carrier to the sheet is generated between the image carrier and the transfer member.
