Abstract
Official abstract text for this publication.
A cleaning blade cleaning the surface of an object includes a rigid holder; and a strip-shaped elastic body fixed on the holder, having a tip ridgeline to contact the surface of the object. The elastic body has a Martens hardness M1 in the range of from 0.9 to 10.0 N/mm 2 at a position 300 μm from the ridgeline on an undersurface of the elastic body including the ridgeline, a Martens hardness M2 at a position 1,000 μm therefrom and a Martens hardness M3 at a position 2,000 μm therefrom, and M1, M2 and M3 satisfy the following relationship: M1>M2>M3.
First claim
Opening claim text (preview).
What is claimed is: 1 . A cleaning blade cleaning the surface of an object, comprising: a rigid holder; and a strip-shaped elastic body fixed on the holder, having a tip ridgeline configured to contact the surface of the object, wherein the elastic body has a Martens hardness M1 in the range of from 0.9 to 10.0 N/mm 2 at a position 300 μm from the ridgeline on an undersurface of the elastic body including the ridgeline, a Martens hardness M2 at a position 1,000 μm therefrom and a Martens hardness M3 at a position 2,000 μm therefrom, and M1, M2 and M3 satisfy the following relationship: M1>M2>M3. 2 . The cleaning blade of claim 1 , wherein the Martens hardness M3 is from 0.3 to 0.7 N/mm 2 . 3 . The cleaning blade of claim 1 , wherein the elastic body comprises a polyurethane rubber and an acrylic curing resin. 4 . The cleaning blade of claim 1 , wherein the elastic body comprises an acrylic curing resin film on the undersurface thereof including the ridgeline. 5 . An image forming apparatus, comprising: an image bearer; a transferer configured to transfer an image formed on the image bearer onto a recording medium; and a cleaning member configured to contact the surface of the image bearer to remove adherents adhering thereto, wherein the cleaning member is the cleaning blade according to claim 1 . 6 . A process cartridge detachably mountable on image forming apparatus, comprising: an image bearer; a transferer configured to transfer an image formed on the image bearer onto a recording medium; and a cleaning member configured to contact the surface of the image bearer to remove adherents adhering thereto, wherein the cleaning member is the cleaning blade according to claim 1 .
