a second container configured to house the liquid transferred from the first container; a transfer unit configured to transfer the liquid from the first container to the second container; and a controller configured to control the transfer unit to intermittently and repeatedly execute a transfer operation of starting transfer of the liquid and then completing the transfer before a side of the bag portion toward the transfer unit transitions to a suction contact state upon transferring the liquid from the first container to the second container. ## Claims ### Claim 1 A transfer device comprising: a first container including a bag portion configured to house liquid; a second container configured to house the liquid transferred from the first container; a transfer unit configured to transfer the liquid from the first container to the second container; and a controller configured to control the transfer unit to intermittently and repeatedly execute a transfer operation of starting transfer of the liquid and then completing the transfer before a side of the bag portion toward the transfer unit transitions to a suction contact state upon transferring the liquid from the first container to the second container, wherein the controller is configured to determine a time of each transfer operation depending on a cumulative time of executed transfer operations preceding a start of each transfer operation. ### Claim 2 (depends on 1) The transfer device according to claim 1, wherein the controller is configured to determine the time of each transfer operation depending on an amount of the liquid in the bag portion at start of the transfer operation. ### Claim 3 (depends on 2) The transfer device according to claim 2, wherein the controller is configured to determine a suspension time between each two successive transfer operations depending on an amount of the liquid in the bag portion. ### Claim 4 (depends on 2) The transfer device according to claim 2, wherein the controller is configured to control a transfer agitation unit to perform an agitation operation of agitating ink in the second container subsequent to each transfer operation. ### Claim 5 (depends on 4) The transfer device according to claim 4, wherein the first container and the second container remain fluidly connected to the transfer unit during each agitation operation. ### Claim 6 (depends on 1) The transfer device according to claim 1, wherein the controller is configured to determine a suspension time between each two successive transfer operations depending on an amount of the liquid in the bag portion. ### Claim 7 A transfer device comprising: a first container including a bag portion configured to house liquid; a second container configured to house the liquid transferred from the first container; a transfer unit configured to transfer the liquid from the first container to the second container; and a controller configured to control the transfer unit to intermittently and repeatedly execute a transfer operation of starting transfer of the liquid and then completing the transfer before a side of the bag portion toward the transfer unit transitions to a suction contact state upon transferring the liquid from the first container to the second container, wherein the controller is configured to determine a time of each transfer operation depending on an amount of the liquid in the bag portion at start of the transfer operation or a type of the liquid. ### Claim 8 (depends on 7) The transfer device according to claim 7, wherein the controller is configured to determine a suspension time between each two successive transfer operations depending on an amount of the liquid in the bag portion. ### Claim 9 A transfer device comprising: a first container including a bag portion configured to house liquid; a second container configured to house the liquid transferred from the first container; a transfer unit configured to transfer the liquid from the first container to the second container; and a controller configured to control the transfer unit to intermittently and repeatedly execute a transfer operation of starting transfer of the liquid and then completing the transfer before a side of the bag portion toward the transfer unit transitions to a suction contact state upon transferring the liquid from the first container to the second container, wherein the controller is configured to determine a suspension time between each two successive transfer operations depending on an amount of the liquid in the bag portion.
