发明名称 Beltless tandem-type image forming apparatus
摘要 In a beltless tandem-type image forming apparatus, a plurality of pairs of transfer rollers are placed side by side at intervals along a conveying direction of sheets. A control section independently conveys sheets in sequence through nip sections of respective pairs of transfer rollers driven by a driving section while sequentially transferring images formed by an imaging section onto the sheets. Conveying speeds of the respective pairs of transfer rollers controlled by the driving section are gradually decreased for every pair of transfer rollers from an upstream side toward a downstream side along a conveying direction of the sheets, and consequently, a driving period for driving the respective pairs of transfer rollers to convey each sheet is gradually increased for every pair of transfer rollers from the upstream side toward the downstream side along the conveying direction of the sheets.
