Abstract:
1. A development method in an image forming apparatus wherein an oscillating bias voltage, in which a development-side electrical potential that can apply an electrostatic force to a toner in a development apparatus in a direction from a developer bearing member to an electrostatic latent image bearing member and an opposite development-side electrical potential that can apply an electrostatic force to the toner in a direction from the electrostatic latent image bearing member to the developer bearing member alternate with each other, is applied between the developer bearing member and the electrostatic latent image bearing member so that an electrostatic latent image formed on a surface of the electrostatic latent image bearing member is developed with the toner, the development method comprising: a first application step of initially applying a first electrical potential V a second application step of applying a second electrical potential V wherein an absolute value of the first electrical potential V
