Image forming apparatus and cartridge

A cartridge comprising:

• a casing;
• an image carrier disposed in the casing and configured to be rotated while carrying a developer and transfer the developer onto a recording sheet at a transfer position;
• and
• a separating sheet consisting of a single resin, the separating sheet disposed in the casing and configured to contact the image carrier at a downstream side of a rotating direction of the image carrier with respect to the transfer position to separate the recording sheet from the image carrier,
• wherein the separating sheet includes a first surface opposed to the image carrier which is charged, and a second surface having a roughness greater than a roughness of the first surface, the second surface opposite to the first surface and opposed to a charged developer image which is transferred but not yet fixed on the recording sheet,
• wherein the separating sheet is made of polypropylene, and a surface roughness Ra of the second surface is within a range of 0.2 μm<Ra<0.9 μm.

An image forming apparatus comprising:

• a main body having a casing;
• an image carrier disposed in the casing and configured to be rotated while carrying a developer and transfer a developer image onto a recording sheet at a transfer position;
• and
• a separating sheet consisting of a single resin, the separating sheet disposed in the casing and configured to contact the image carrier at a downstream side of a rotating direction of the image carrier with respect to the transfer position to separate the recording sheet from the image carrier,
• wherein the separating sheet includes a first surface opposed to the image carrier which is charged, and a second surface roughened by a roughening processing, the second surface opposite to the first surface and opposed to a charged developer image which is transferred but not yet fixed on the recording sheet,
• wherein the separating sheet is made of polypropylene, and a surface roughness Ra of the second surface is within a range of 0.2 μm<Ra<0.9 μm.

A cartridge comprising:

• a casing;
• an image carrier disposed in the casing and configured to be rotated while carrying a developer and transfer the developer onto a recording sheet at a transfer position;
• and
• a separating member disposed in the casing and configured to contact the image carrier at a downstream side of a rotating direction of the image carrier with respect to the transfer position to separate the recording sheet from the image carrier,
• wherein the separating member has a sheet shape including a first surface opposed to the image carrier and a second surface opposite to the first surface,
• wherein the second surface is roughened by a roughening processing, and
• wherein the separating member is made of polypropylene, and a surface roughness Ra of the second surface is within a range of 0.2 μm<Ra<0.9 μm.
