Image forming apparatus

An image forming apparatus comprising:

• an image bearing member configured to rotate;
• a charging unit configured to charge a surface of the image bearing member at a charging position;
• a developing unit configured to develop an electrostatic latent image formed on the image bearing member at a development position, the developing unit comprising a developer bearing member configured to rotate while bearing a developer containing a toner and a carrier thereon and configured to be applied a development voltage;
• and
• a control portion configured to perform a first mode and a second mode, the first mode being a mode in which a driving input to the developer bearing member is stopped in response to image formation completion before or at the same time when a trailing end of a charging area of the image bearing member charged by the charging unit reaches the development position, and an application of the development voltage is stopped after the trailing end of the charging area reaches the development position, the second mode being a mode in which the driving input to the developer bearing member is stopped in response to image formation completion before or at the same time when the trailing end of the charging area reaches the development position, and the application of the development voltage is stopped at a timing after the trailing end of the charging area reaches the development position and earlier than that in the first mode, or at the same time when the trailing end of the charging area reaches the development position,
• wherein the control portion is configured to switch the first mode and the second mode based on information which influences a toner charging amount.
