Method and apparatus for printing an appropriate image even on a special recording medium

A method for forming an image, comprising:

• transferring a first visible image from a first belt-formed image bearing member to a send belt-formed image bearing member;
• transferring the first visible image transferred onto the second image bearing member onto a first surface of a recording medium;
• transferring a second visible image from the first image bearing member onto a second surface of the recording medium to form visible images on both surfaces of the recording medium;
• and
• controlling an image forming condition including a fixing condition differently depending on a specific property of a recording medium,
• wherein the first and second belt-formed image bearing members are each intermediate transfer belts, and the second visible image is formed by a plurality of image forming units and is transferred onto the first belt-formed image bearing member while the first belt-formed image bearing member contacts the plurality of image forming units and then the first visible image is formed by the plurality of image forming units and is transferred onto the first belt-formed image bearing member.

A method for forming an image, comprising:

• transferring a first visible image from a first image bearing member to a second image bearing member;
• transferring the first visible image transferred onto the second image bearing member onto a first surface of a recording medium;
• transferring a second visible image from the first image bearing member onto a second surface of the recording medium to form visible images on both surfaces of the recording medium;
• fixing the first and second visible images transferred onto the recording medium while the recording medium is placed in contact with the second image bearing member;
• and
• controlling an image forming condition including a fixing condition differently depending on a specific property of a recording medium.

A method for forming an image, comprising:

• transferring a first image formed on a first surface of a first belt-formed image bearing member to a second belt-formed image bearing member;
• forming a second image on the first surface of the first image bearing member;
• reversing a polarity of the first image transferred onto the second image bearing member;
• transferring the first and second images onto respective surfaces of the recording medium at a same time;
• and
• controlling an image forming condition including a fixing condition differently depending on a specific property of a recording medium,
• wherein the first and second belt-formed image bearing members are each intermediate transfer belts, and the second visible image is formed by a plurality of image forming units and is transferred onto the first belt-formed image bearing member while the first belt-formed image bearing member contacts the plurality of image forming units and then the first visible image is formed by the plurality of image forming units and is transferred onto the first belt-formed image bearing member.

An image forming apparatus, comprising:

• first belt-formed image bearing means for transferring a first visible image onto a first surface of a recording medium;
• and
• second belt-formed image bearing means for transferring a second visible image that has been transferred from the first image bearing means onto a second surface of the recording medium such that visible images are transferred onto both surfaces of the recording medium, wherein an image forming condition including a fixing condition is controlled differently depending on a specific property of a recording medium;
• wherein the first and second belt-formed image bearing means are each intermediate transfer belts, and the second visible image is formed by a plurality of image forming means and is transferred onto the first belt-formed image bearing means while the first belt-formed image bearing means contacts the plurality of image forming means and then the first visible image is formed by the plurality of image forming means and is transferred onto the first belt-formed image bearing means.

A method for forming an image, comprising:

• transferring a first visible image from a first belt-formed image bearing member onto a second belt-formed image bearing member;
• transferring the first visible image transferred onto the second image bearing member onto a first surface of a recording medium;
• transferring a second visible image from the first image bearing member onto the second surface of the recording medium to form visible images on both surfaces of the recording medium;
• and
• controlling an image forming condition based on a length of the recording medium,
• wherein the first and second belt-formed image bearing members are each intermediate transfer belts, and the second visible image is formed by a plurality of image forming units and is transferred onto the first belt-formed image bearing member while the first belt-formed image bearing member contacts the plurality of image forming units and then the first visible image is formed by the plurality of image forming units and is transferred onto the first belt-formed image bearing member.

A method for forming an image, comprising:

• transferring a first visible image from a first image bearing member onto a second image bearing member;
• transferring the first visible image transferred onto the second image bearing member onto a first surface of a recording medium;
• transferring a second visible image from the first image bearing member onto the second surface of the recording medium to form visible images on both surfaces of the recording medium;
• fixing the visible images transferred onto the recording medium while the recording medium is placed on the second image bearing member;
• and
• controlling an image forming condition based on a length of the recording medium.

A method for forming an image, comprising:

• transferring a first image formed on a first surface of a first belt-formed image bearing member onto a second belt-formed image bearing member;
• forming a second image on the first surface of the first image bearing member;
• reversing a polarity of the first image transferring onto the second image bearing member;
• transferring the first and second images onto respective surfaces of a recording medium at a same time;
• and
• controlling an image forming condition based on a length of the recording medium,
• wherein the first and second belt-formed image bearing members are each intermediate transfer belts, and the second visible image is formed by a plurality of image forming units and is transferred onto the first belt-formed image bearing member while the first belt-formed image bearing member contacts the plurality of image forming units and then the first visible image is formed by the plurality of image forming units and is transferred onto the first belt-formed image bearing member.
