    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.

    摘要翻译： 提供一种图像形成装置，其包括图像载体，对图像载体进行充电的充电器，在图像载体上形成静电潜像的潜像形成装置，用调色剂显影静电潜像的显影装置， 转印装置将调色剂图像转印到转印介质上，以及清洁刮板以除去留在图像承载体上的剩余调色剂颗粒。 调色剂包括粘合剂树脂和脱模剂。 脱模剂在调色剂中具有最长的长度Lmax，其等于或大于调色剂的最大Feret直径Df的1.1倍。 清洁刮板包括具有与图像承载体的接触部分的条状弹性体刀片。 接触部分包括具有脂环结构的丙烯酸酯或甲基丙烯酸酯化合物的紫外线固化性组合物的固化物。
