Abstract
A process for producing a transfer member to be used in a transfer system in which a toner image formed on a first image-bearing member is transferred to a second image-bearing member includes the steps of melt-extruding an extrusion material from a circular die of an extrusion/forming apparatus into a cylindrical film; and measuring the circumference of the cylindrical film and sending the resultant information to the extrusion/forming apparatus to adjust the circumference of the cylindrical film. A transfer member is produced by such a process, and an image-forming apparatus uses the transfer member. The transfer member can be produced either as an intermediate transfer belt or a transfer belt which has a stable peripheral length.

A process for producing a transfer member to be used in a transfer system by which a toner image formed on a first image-bearing member is transferred to a second image-bearing member, the process comprising the steps of;
- melt-extruding an extrusion material from a circular die of an extrusion/forming apparatus into a cylindrical film;
- and
- measuring a circumference of the cylindrical film and sending the resultant information to the extrusion/forming apparatus to adjust a circumference of the cylindrical film,
- wherein the extrusion material has a water absorption of 1.9% or less.
A transfer member to be used in a transfer system by which a toner image formed on a first image-bearing member is transferred to a second image-bearing member, the transfer member comprising a cylindrical film obtained by;
- melt-extruding an extrusion material from a circular die of an extrusion/forming apparatus into a cylindrical film;
- and
- measuring a circumference of the cylindrical film and sending the resultant information to the extrusion/forming apparatus to adjust the circumference of the cylindrical film,
- wherein said extrusion material has a water absorption of 1.9% or less.
