Publication number: 20230305428Abstract: An image forming apparatus includes an image bearing member and a developer bearing member. A first period is from when rotational drive of the developer bearing member is started until increased to a speed at which the image forming apparatus performs image forming. A first absolute value of a difference between a developer bearing member surface potential Vdc and an image bearing member surface potential Vd, as determined when the image bearing member is facing the developer bearing member, is obtained during the first period. The value |Vdc?Vd| obtained during the first period is smaller than the value |Vdc?Vd| obtained after the first period. During the first period, the image bearing member surface potential Vd at the facing position is a first potential and, after the first period, the image bearing member surface potential Vd at the facing position becomes a second potential different from the first potential.Type: ApplicationFiled: March 13, 2023Publication date: September 28, 2023Inventors: TATSUYA KOHNO, TAKAHITO FUSE, ATSUSHI MATSUMOTO, HIROAKI ISHIDA
