Abstract:
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.
