ABSTRACT:
An image forming apparatus has: an image bearing member which bears a toner image; a transfer member which comes into pressure contact with the image bearing member and transfers the toner image on the image bearing member onto a recording material; a first cleaning member which electrostatically collects the toner on the transfer member; and a second cleaning member which electrostatically collects the toner on the first cleaning member, wherein when a ratio of an amount of toner which is adsorbed by the first cleaning member to an amount of toner on the transfer member is assumed to be α(%) and a ratio of an amount of toner which is adsorbed by the second cleaning member to an amount of toner on the first cleaning member is assumed to be β(%), α>90(%), β>90(%), and α≦β.
