Abstract: A communication system in which a primary base station or a secondary base station communicates with a mobile terminal. The primary base station sends the mobile terminal and the secondary base station an announcement signal which includes identification information for identifying a cell of the primary base station. When receiving the announcement signal, the secondary base station sends the mobile terminal a pseudo announcement signal which includes the identification information and adjacent cell information which includes information for a cell of the secondary base station. When receiving the announcement signal and the pseudo announcement signal, the mobile terminal compares a reception power of the signal received from the primary base station with that of the signal received from the secondary base station, and performs communication with one of the base stations which has higher power.

Abstract: An image forming apparatus includes a toner-image carrying member, a transfer unit that transfers the toner image on the toner-image carrying member onto a recording medium at a transfer portion, a transport roller disposed along a transport direction to transport the recording medium to the transfer portion while being in contact with the recording medium, and a release unit that releases the contact of the transport roller with the recording medium. The release unit does not release the contact of the transport roller when it is detected that the recording medium passing through the transport roller is a thick recording medium or a recording medium having a high bending strength, and releases the contact when the recording medium is different from the thick recording medium and the recording medium having a high bending strength. The release unit releases the contact before a leading edge of the recording medium reaches the transfer portion.
