IMAGE FORMING DEVICE

摘要

This is an image forming device for supplying a developing agent to a developing section for developing a latent image in an electrophotographing apparatus and the like. A developing agent supply member (37) is formed of a soft foamed synthetic resin material provided with electric conductivity, in which, out of the values of its physical properties, when F = S. rho /H, where hardness is H (kgf), density is rho (kg/m<3>) and the number of cells is S (cell/inch), then F is set to 72 to 114. Or, a movement velocity of the developping agent supply member (37) at a contact portion (3) is set at 1.4 to 1.7 times the movement velocity of a developing agent conveying member (32). Due to this, an optimum amount of the developing agent can be supplied to the developing agent conveying member for conveying the developing agent to the developing section, so that a good printing quality can be obtained.
