Abstract
An electrostatic latent image developing apparatus includes an agitating member accommodated in a casing, a roller member accommodated in a front of the casing, and a blade contacting under pressure with an outer circumferential portion of the roller member, which is arranged in the casing. Toner held on the outer circumferential portion of said roller member being supplied to develop an electrostatic latent image on the basis of rotation of the roller member while being regulated by the blade. The apparatus includes a partition member arranged between the roller member and the agitating member at an upper stream side of said blade corresponding to a rotary direction of the roller member. The casing has a space defined among the partition member, the blade, and the outer circumferential portion of the roller member.
