Transfer device including fastener to fasten a holder portion and another holder portion which has a higher rigidity than the holder portion

A transfer device comprising:

• a belt;
• a transferor movable to contact the belt;
• a holder to hold the transferor;
• a biasing structure to bias the transferor toward the belt;
• and
• a movement structure to contact the holder and cause the transferor to move in a direction opposite to a direction in which the biasing structure biases the transferor,
• the holder including:
• a contact portion to contact the movement structure;
• and
• a holder portion, and
• the contact portion comprising a material having a higher rigidity than the holder portion,
• wherein the holder further includes attachment portion to which the biasing structure is attached, and said attachment portion includes a material having a higher rigidity than the holder portion,
• wherein the holder includes another holder portion, and said another holder portion includes the contact portion and the attachment portion as a single component, and
• wherein the transfer device further comprises a fastener to fasten the holder portion and said another holder portion to each other, the holder includes a rotation shaft and is rotatable around the rotation shaft, and the fastener fastens the holder portion and said another holder portion in a direction parallel to a direction in which the biasing structure biases the holder.
