摘要:
Provided is an image bearing member protecting agent which contains a fatty acid metal salt and an inorganic lubricant, wherein an aspect ratio (average major axis length/average minor axis length) of the inorganic lubricant is 60 to 400, and a mass ratio of the fatty acid metal salt to the inorganic lubricant (fatty acid metal salt/inorganic lubricant) is 98/2 to 85/15.
摘要:
An image bearing member includes a substrate, a photosensitive layer overlying the substrate; and a surface layer overlying the photosensitive layer, wherein the surface layer includes a cross-linked layer formed by curing a radical polymerizable monomer having no charge transport structure and a radical polymerizable compound having a charge transport structure, wherein a protective agent is supplied to the surface layer by a protective agent supplying member which is arranged facing the surface layer and includes a roller having a core material and a foam layer thereon to form a protective layer on the surface layer.

An image forming apparatus, including: an image bearing member; and a protective layer forming unit which includes a protective agent supplying member which rotatably contacts a surface of the image bearing member and an image bearing member protective agent, wherein the image bearing member protective agent includes at least a metal salt of a fatty acid and an inorganic lubricant, wherein the protective agent supplying member includes: a core material; and a foam layer formed on an outer periphery of the core material and including a plurality of cells, and wherein drive torque of the image bearing member and drive torque of the protective agent supplying member satisfy Formula (1) below: 1.47×10−4≦[(A1+B1)−(A0+B0)]/L[N·m/mm]≦1.96×10−3 Formula (1)
摘要:
A protective layer forming device, including: a powdery image bearer protecting agent formed of a granulated product containing a fatty acid metal salt and an inorganic lubricant; and a roller-shaped protecting agent supplying member configured to supply the powdery image bearer protecting agent to a surface of an image bearer.
摘要:
An image bearer protective agent is provided. The image bearer protective agent includes a fatty acid metal salt and an inorganic lubricant. The inorganic lubricant includes a first inorganic lubricant having a tap density of from 0.30 to 0.8 g/cm2.
摘要:
An image forming apparatus is provided. The image forming apparatus includes an image bearer and a cleaning blade configured to remove toner particles remaining on the image bearer. The cleaning blade includes an elastic member in contact with a surface of the image bearer to remove the toner particles. The elastic member has a Martens hardness of from 3 to 8 N/mm2 when measured by a nanoindentation method with a load of 1 μN. The toner particles comprise toner base particles and an external additive, and the external additive comprise silica particles. A liberation ratio (Xs) of the silica particles liberated from the toner particles is from 40% to 75% when measured by an ultrasonic vibration method. A proportion (R70) of the silica particles having a volume-based particle diameter of 70 nm or more in the silica particles liberated from the toner particles is from 70% to 90% by number.
