    摘要： An image forming apparatus is provided which includes an image bearer, a charger to charge the image bearer, a latent image forming device to form an electrostatic latent image on the image bearer, a developing device to develop the electrostatic latent image with a toner, a transfer device to transfer the toner image onto a transfer medium, and a cleaning blade to remove residual toner particles remaining on the image bearer. The toner includes a binder resin and a release agent. The release agent has a longest length Lmax in the toner, which is equal to or greater than 1.1 times a maximum Feret diameter Df of the toner. The cleaning blade includes a strip-like elastic body blade having a contact part with the image bearer. The contact part includes a cured product of an ultraviolet curable composition including an acrylate or methacrylate compound having an alicyclic structure.

    摘要： A cleaning blade includes a supporting member, and a tabular elastic member. One end portion of the elastic member is fixed to the supporting member, and the other end portion is a free end portion whose tip edge is to be contacted with a member to be cleaned while rubbing the surface to remove a residual material therefrom. The tip portion of the free end portion of the elastic member ranging in length from 0 to 500 μm from the tip surface thereof includes at least a cured material of a curable compound and an elastic material of the elastic member. The elastic member satisfies the relationship, 0.05(%)≦[(tM−tA)/tA]×100≦2%, wherein tM represents the maximum thickness of the tip portion of the elastic member, and tA represents the average thickness of the rear portion of the free end portion of the elastic member.
